Find the indicated trigonometric value in the specified quad

Find the indicated trigonometric value in the specified quadrant.

Function Value		Quadrant		Trigonometric Value
tan = 8/7		III		sec

tan = 8/7 Q-III

Hypoteuse = sqrt( 7^2 + 8^2) = 10.63

cos = - 7/10.63 ( cos is -ve in IIIrd)

sec = -1/cos = -10.63/7 = -1.52
