Q: (a) Evaluate| cos (4x) -dx. (1+ 2sin ( n(4x)*

A:

Q: sinx = 5/13, x E 5,1], then cosx =?

A: We are solving the problem by the property of trigonometry ratio.

Q: Is (1-sin x) not the same as (sin x - 1)?

A: (x - y) is not same as (y - x), whereas  (x - y) = - (y - x)

Q: Differentiate. f(x) = x cos(x) sin(x) (please write it out on paper)

A:

Q: 4 cos x + 2 sin r = 2 COS

A: As we know, Sin2x + cos2 x = 1 Since the interval is not given so we have to find general solution

Q: sin( – x) = cos x = COS X

A: Given: To prove that sin(π2-x)=cos x

A:

Q: Explain how to transform sin x into the function f(x) = -sin x. 4

A: To transform the function sin(x) into the function f(x) =-14sin x, we can apply a vertical stretch…

Q: Let F= (2e", 5 sin(x), 8 cos(x)). Calculate div(F) and curl(F). (Use symbolic notation and fractions…

A:

Q: cos x sin x = csc 2x cos 3x sec 2x

A:

Q: If () Z = tan || then 2z sin x 1+ z2

A:

Q: Verify the identity sin t - cos 2t = (2 sin t - 1)(sin t + 1).

A: sin t - cos 2t=(2sin t-1)(sin t +1)Formulascos 2t= 1-2sin2t

A:

Q: FIX) = sin(x+ cos x) -0.5=0 Find F(X), F(x)

A:

Q: sin x − 1 = cos x − 1

A:

Q: Rewrite cos ( x –) in terms of sin(x) and cos(x) 3

A: we know that cos(x-y)=cos(x)cos(y)+sin(x)sin(y)

Q: rewrite cos(x+4pi/3) in terms of sin(x) and cos(x)

A:
