Problem Problem 5
Let x = 60 and y = 45 in each of the following expressions, and then simplify each expression as much as possible. a. 3 sin x b. cos 2y c. 5 sin (3x 90)
Step-by-Step Solution:
Step 1 of 3
L8 - 4 We are using an important result: If f and g are functions so that f(x)= g(x)ofrl x ▯= c, and x→c g(x)ei,enl x→c f(x)=m lx→c g(x). So if h(x)= f(x) and both f(x)a d g(x)apah0as g(x) 0 x → c, the indeterminate form 0,eusri techniques to find a function equivalent to h(x)extat x = c. √ ex. Evaluate: lim x − 12 − x x→3 x − 3
