1.) Rewrite with only sin x and cos x. sin 3x A.)2 sin x cos2x + cos x B.)2 sin x cos2x + sin3x C.)sin x cos2x - sin3x + cos3x D.)2 cos2x sin x + sin x - 2 sin3x 2.) Find the exact value by using a half-angle identity. sin(7pi/8)let's see if we can take the indefinite integral of sine squared X cosine to the third X DX and like always pause the video and see if you can work it through on your own alright so right when you look at it you're like oh wow if this was just a sine of X not a sine squared of X well that's going to be the derivative of the derivative of cosine of X maybe I could abuse u-substitution likewisecos 3x can be written using the sum and difference identity. cos (3x) = cos (2x + 1) cosx * cos2x - sinx * sin2x next, you have to use the double angle identities for both sine and cosine. there are three options for cosine, so choose one.5. Rewrite sin^4(3x) into an expression with no powers. 6. Verify the identity: cos(x + y)cos(x−y) = cos^2(x)−sin^2(y) 7. Write down the difference quotient for f(x) = cos(x), and rewrite the expression in the following form: cos(x)·a(h)+sin(x)·b(h), where a(h) and b(h) are functions of h. Simplify. 8. Solve the equation on the intervalRewrite with only sin x and cos x. sin 3x

Frequently students ask why can't I work a double angle problem in the following way. Suppose I am given sin(x) = 0.2, x is in Quadrant 1, and I am asked to find sin(2x).With a calculator, I can find the angle x (it's approximately 11.537 o), double it (to get 23.074 o), and then take the sine of that angle (0.3919).There is nothing wrong with this in practice.What I have so far: rewrite the problem as a product of two squared terms: $\sin^2(x)\sin^2(x)$ Apply the squared identity for sine twice: $(1+\cos(x)) (1-\cos(x)) (1+\cos(x)) (1-\cos(x))$It can be rewritten in terms of two addition identities: sin(u + v) = sinucosv + cosusinv cos(u +v) = cosucosv −sinusinv sin(3x) = sin(2x +x)Answer to QUESTION 18 Rewrite with only sin x and cos x. sin 3x - cos 2x 2 sin x cos2 x - sin x + 2 sin3 x + 1 - 2 sin2x 2 sin x c...the options are a. cos x - 4 cos x sin^2x b. -sin^3x + 2 sin x cos x c. -sin2x + 2 sin x cos x d. 2 sin2x cos x - 2 sin x cos x please help tell me what letter is your final answer
understand that
sin(a +b) = sin(a) cos(b) + sin(b) cos (a) call this #1
if a and b are both =x then sin (x + x) = 2sinx cosx name this #2
and cos2x = 1 - 2sin2x call this #3
sin(3x) =sinx (2x + x)
= sin2x cosx + sinx cos 2x the usage of #1
= (2cosx sinx)(cos x) + sinx (1 - 2sin2x) using #2 and #3
=2cos2x sinx + sinx - 2sin3x
