ADITIONAL INFORMATION

COS THETA = 1/SEC THETHA.

Answer 2

Answer:

We have ,

sec^2 theta = 1 + tan^2 theta

sec^2 theta = 1 + ( 3/4 )^2

sec^2 theta = 1 + 9/16 = 16+9/16 = 25/16

sec theta = root 25/16 = 5/4

NOW

cos theta = 1/sec theta

cos theta = 1/(5/4)

cos theta = 4/5

Thus , the value of sec theta and cos theta are

5/4 AND 4/5 respectively .
