== == Cos2x - 1 = [1 - 2sin2 x] - 1 = - 2sin2 x; so [Cos2x - 1] / x = -2 [sinx] [sinx / x] As x approaches 0, sinx / x app 1 while 2 sinx app 0; hence the limit is 0.
Evaluate -4(a+b) - 10a/b when a=8 and b=5

Evaluate -4(a+b) - 10a/b when a=8 and b=5
The answer is x = 5. There is nothing to evaluate there!

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
16 lol?

to evaluate 5 squared you must simply do 5x5. Which equals 25.
Evaluate 9p + 33 for p = 5
