Prove that; sin3(theta)=3sin(theta)-4sin^3(thet a) show your solution.

The problem ask to prove that the two equation or trigonometric functions are similar and congruent to each other , so base on the data in your problem and by following certain theories about the said trigonometric functions, the answer would be sin3x = sin(2x + x) = sin2x cos x + cos2xsinx, I hope this would help you 

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

Can you explain what u need
