Find the value of if is in the second quadrant and
Find the value of if is in the third quadrant and
Find the value of if and .
(a) Given sin a = 24/25 and a is in the second quadrant . Draw a triangle with opposite side 24 and hypothenus 25 , so the adjacent side will be -7 .
cos a is negative here = -7/25
(b) Can u try this one .
(c) Given cos a is negative and sin a is postitive . Thus the angle will be in the 2nd quadrant . sin a =24/25
THis is the same as (a) .
