Answer 2

It is similar to previous question.
Here you are given d(theta)/dt instead and you need to find value of AP.
Same procedure. Give it a try and tell me if you get stuck anywhere

Answer 3

sure..

Answer 4

converted 45deg to radians.. its 1/4pi

Answer 5

excellent, you have done everything correct till now.
h' = 200 sec^2 (theta) theta'
you have given value of theta = 45 degrees. You can calculate cos(theta) from there, and thus sec(theta)
you have also been given value of theta'
just need to find h' .

Answer 6

i triend sec theta.. and i got syntx error lol

Answer 7

*tried*

Answer 8

cos(45) = 1/sqrt2
and sec(theta) = 1/cos(theta)

Answer 9

so you getting to the ans now ?

Answer 10

that is right. but how is this info useful here ?

Answer 11

how am i going to substitute it? =)

Answer 12

h' = 200 sec^2 (theta) theta'
h' you need to find out
sec(theta) = sqrt2
theta' = 0.9

Answer 13

correct (Y)

Answer 14

Thank you so much!!!
