What is the value of **period** **of** 2 sin **x** **cos** **x**? Let the given function be y = 2 sin **x** **cos** **x**. Thus, y = sin 2x. We know that the **period** **of** sin ax is 2π/a. The **period** **of** sin 2x = 2π/2 = π. Therefore, the **period** **of** 2 sin **x** **cos** **x** is π. 16 hours ago · A has a sine graph with and amplitude of 0 31cm, B = 107 y = –2 sin **x** 6 Graphing Sine And Cosine Functions Worksheet Answers in an understanding moderate may be used to try pupils skills and knowledge by addressing questions sine function: amplitude = 15, **period** = 4𝜋, phase shift = 𝜋⁄2, vertical shift = –10 2 sine function: amplitude = 15, **period** = 4𝜋, phase. 1. **Period** **of** y=sin **x**. 2π. **Period** **of** y=cos **x**. 2π. **Period** **of** y=tan **x**. π. **Period** **of** y=cot **x**. π.

The **period** **of** the sine curve is the length of one cycle of the curve. The natural **period** **of** the sine curve is 2π. So a coefficient of b=1 is equivalent to a **period** **of** 2π. To get the **period** **of** the sine curve for any coefficient b just divide 2π by the coefficient b to get the new **period** **of** the curve. Note: The **period** of the cosine function is $2\pi .$ That is, the **period** of **$\cos x**=2\pi .$ The **period** of the sine function is also $2\pi .$ That is, the **period** of $\sin **x**=2\pi .$ The **period** can be found as follows: **Period** of **$\cos \left( \cos x** \right)=\pi $ and $\**cos** \left( \sin **x** \right)=\pi .$.

For the first one, a function f(**x**) is periodic, with a **period** of T if f(**x**) = f(**x** + T). You can use this fact to solve your first problem: [tex]\**cos**^2(**x**) = \**cos**^2(**x** + T)[/tex] A useful identity is [tex]\**cos**^2x = \frac{1}{2}\left(1 + \**cos**{2x})[/tex]. Use that identity on both sides of the above equation, then group terms in **x**. Identify the **period** **of** g(x) = **cos** 8π. Then graph the. Identify the **period** **of** g(x) = **cos** 8π. Then graph the function and describe the graph of g as a transformation of the graph of f(x) = **cos** π. Show Answer. Create an account. Get free access to expert answers.

Trigonometry. Find Amplitude, Period, and Phase Shift** y=cos (x)** y =** cos (x)** y =** cos ( x)** Use the** form acos(bx−c)+** d a cos ( b x - c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 1 a = 1. b = 1 b = 1. c = 0. Answer: We want to determine the **period** of **\cos** (\sin **x**). When we consider **x** as the variable, the domain of **\cos** (\sin **x**) is the set of real numbers, R. However, if we consider \sin **x** as the variable, the domain of **\cos** (\sin **x**) is [-1,1]. So, one can look at the function y = \**cos** (\sin **x**) as. The **period** T = LCM {**period** **of** sin **x**, **period** **of** **cos** **x**} = 2 π Whenever there is a trigonometric function involved, after finding T , always check whether the T 2 is a **period** or not. When **period** p = π , then. Jan 04, 2022 · Our function, f(x) = 3 sin(4x + 2), is a sine function, so the **period** would be 2 pi divided by 4.

So **period** of f(**x**) will be L.C.M of all **period** = 1. Similar Questions If y = 2[**x**] + 3 & y = 3[**x** – 2] + 5, then find [**x** + y] where [.] denotes greatest integer function. 41,847. 969. dextercioby said: T=2 s. Don't forget the units. "s"? What is "s"? The problem, as stated, does not have units- it is a pure function. Even if you assume "t" is time (I would not, I see no reason to assume this is a physics problem rather than a mathematics problem) why would you assume the units are seconds rather than minutes or. Trigonometry Functions (Check out our worksheet with the six trigonometric functions answer key). Sine = Sin. Cosine = **Cos**. Tangent = Tan. Secant = Sec. Cosecant = CSC. Cotangent. FINDING SINE AND COSINE RATIOS Find the unknown side length . Then find sin **X** and **cos X**. Write each answer as a fraction in simplest form and as a decimal. Round to four decimal places, if necessary. 22. 14 Y Z **X** 7 3 23. Z 8 2 Y **X** 4 24. 35 12 Z.

In y=cos(x), the **period** is 2π. We can confirm this by looking at the peaks in the cosine graph. At x=0, y=cos(x) has a peak. The first time another peak occurs on the function is at x=±2π, confirming that the **period** **of** cosine is 2π. Compared to y=cos(x), shown in purple below, which has a **period** **of** 2π, y=cos(2x) (red) has a.
