Question

simplify the trigonometric expression?
sin^2(theta)/1- cos(theta)

Answer 1

trig identity
sin^2 theta = what ?

Answer 2

Just a suggestion, but go to mathway.com and it solves most problems your stuck on and helps break stuff down

Answer 3

i know sin (theta) = 1/csc(theta)

Answer 4

just becareful sometimes it will give u the wrong answer
js :)

Answer 5

identity
\[\huge\rm sin^2 \theta + \cos^2 \theta = 1 \]
solve this for sin^2 theta

Answer 6

oh yeah, i forgot about that!
sin^2 (theta) = 1-cos^2(theta)

Answer 7

Yeah you have to be exact with it and sometimes it wont give you the answer so, Yeah:) very helpful though still

Answer 8

yep right now apply difference of square method \[\huge\rm a^2 - b^2 = (a+b)(a-b)\]

Answer 9

(1 + cos (theta))(1-cos(theta))?

Answer 10

so the answer is 1 + cos(theta)?

Answer 11

yep right \[\huge\rm \frac{ (1 - \cos \theta )(1+ \cos \theta)}{ 1-\cos \theta }\]

Answer 12

yes right

Answer 13

cuz 1 - cos(theta) cancels out

Answer 14

thanks!

Answer 15

np :-)
