The answer is the hypotenuse of the right angle triangle which is equal to the square-root of the sum of squares of 15 and 8. So the answer is 17
Differentiate y = 3 sin x - 4 cos x
The derivative of sinx is cosx and the derivative of cosx is -sinx the answer is 3 cosx+4sinx
If x <2, simplify |x - 2| - 4|-6|
Given the expression |x - 2| - 4|-6| If x < ;2 then x - 2 < 2 and if x - 2 < 2 the |x - 2| = -(x - 2). Substitute |x - 2| by -(x - 2) and |-6| by 6 . |x - 2| - 4|-6| = -(x - 2) -4(6) = -x -22
