Question regarding limits to see if my procedure of getting the answer is

limit x-> 0

tan(x^2)

x

i know it's indeterminate so i need find another way

so i did the tan identity

cosx^2

sinx^2

x

cosx^2 1
*
sinx^2 x

cosx^2

sinx^3

i don't know what to do, but i know that it has to be 0. any ideas?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

Two numbers have a sum of -19. one number is x. what expression represents the other number?
