Let L be any positive number. Consider the functions sin(x) and cos(x)

Q: X 25 24 7

A:

Q: tanx dx cos²x

A: Given that: ∫tanxcos2xdx

Q: Apply Newton’s approx. to find the value of x for cos x = sin x; x0 = 1.

A: Topic-  Numerical Analysis. Newton's approximation Formula: xn+1 = xn - f ( xn)f' (xn)

Q: 5. Use substitution to find S sin1º0 cos 0 d0.

A: We will find the integration.

Q: Let x be a real number between 9 and 11. Provide an expression for sin(cos-(x - 10)) (in terms of x)…

A:

Q: Xp

A:

Q: -1 x-1 +tan x+ n(-7) tan T+tan x-1

A: Introduction :

Q: Is the function f(x)=sin(3x)+cos(tan x) even, odd, or neither? Why?

A: Recall: A function f(x) is even if  f(x) =f(-x). A function f(x) is odd if f(x)=-f(-x)

Q: Ex2: Use the identities 4 and 5 to prove that: cos(x- y)-cos(x+y) (a) sin x sin y = 2

A: Formula used -  cos(A-B) = cosA cosB + sinA sinB  cos (A+B) = cosA cosB - sinA sinB

Q: Evaluate Jx/2 6 sin x (cos x + 1)³ dx

A:

Q: 5. Write the trigonometric expression as an algebraic expression. Show all work. sin [sin-(x) +…

A: The given expression,      sinsin-1x+cos-13x

Q: for what value of x is cosx 1=5cosx is true

A: Solution: Consider the given equation: cos x .1 = 5 cos x Therefore, 5 cos x = cos x5 cos x - cos x…
