    solve it by using matlab Question 2) (2.5 points) Examine the following trigonometric identity: sin'(x) = (3 sin(a) – sin(3.c)) Verify that this identity is valid. To do so, define a variable x as x = 84 (in degrees!). Compute the left and right sides of the identity and assign them to variables p2left and p2right. Because x is in degrees, make sure you are using the correct trig function! Use the help function if you are unsure. Question 1)...
