Question

find the values of the remaining trigonometric funtions a theta from the given information. a) sin theta = 5/13 , cos theta = -12/13 b) cos theta = -3/5 , tan theta < 0

hartnn · Answer

good
do you want to use standard relations or the triangle method ?

hartnn · Answer

you know standard relations like 
sec x = 1/cos x , tan x = sin x/ cos x and all ?
or are you comfortable with drawing a right triangle ?

hartnn · Answer

you still there ?

anonymous · Answer

im still here!

anonymous · Answer

yea drawing the right triangle

anonymous · Answer

i want to use the triangle method

hartnn · Answer

good, go ahead and draw the triangle

anonymous · Answer

i need help on how to find the values

hartnn · Answer

sin theta = 5/13 

you know that sin of angle = opposite side/ hypotenuse 
right ???
so draw a right triangle using this info., can u ?

anonymous · Answer

is that correct?

hartnn · Answer

-5 ?
side length cannot be negative
and which angle is theta ?

anonymous · Answer

i meant 5 sorry 
the angle which is theta is sin ? opposite of hypotenuse
