then I'm going to cancel out cos tan(2) SO simplifies to sin(x) sec(x) cos(x)-sin(x) Simplify cos(x)+sin(x) Reply | 1 Reply, 1 Unread Edit View Insert Format Format Tools Table 12pt Paragraph BIU

Use basic identities to simplify cos^3 x+sin^2 x cos x.   Enclose arguments of functions in parentheses. For example, sin(2x). Remember that writing sin(x) to the fourth power as sin^4(x) is just a mathematical shorthand. You should write it as (sin(x))^4, which is what Mobius expects.   cos^3 x + sin^2 x cos x =   can you please help me better understand this question and how you arrived at the answers? Im having a difficult time in trig and desperately need help..

write sin(3x)cos(6x) + cos(3x)sin(6x) as a single trig function

simplify a. sin^2(3x)+cos^2(3x) b. cos^2(3x)-sin^2(3x)

Use the cofunction identities to select the correct answer which fills in the blank. cos(10x) = sin_ O cos(10x) = sin(180° + 10x) O cos(10x) = sin(180° – 10x) O cos(10x) = sin(90° + 10x) O cos(10x) = sin(10x – 90°) O cos(10x) sin(90° – 10x)

Find all solutions of the following equation in the interval [0, 2π).    sin^3x=sinx

Prove this equation (cosx-sinx) ^2=1-2sinxcosx

Differentiate  cos(t^2 - 6)

Evaluate the expression without a calculator. Show all work.sec[(sin^(-1))((-1)/5)] Solve the equation for all solutions over the interval [0°, 360°). (Hint: the period of tan(??) is 180° so there are 4 solution. Also make sure your calculator is in degrees.) Show all work.3tan2(?)−3tan(?)−1=0

Simplify sin-1(sin(x)) if -?/2 ≤ x ≤ ?/2. sin-1(sin(x))=
