(1) sin A = COS DU tan A=cot B Hs 15g 1 A+B =90°

If tan A= cot B, prove that A+ B = 90^(@)

If tan A= cot B. prove that : A+B =90^(@)

If tan A = cot B. prove that A +B = 90^@ .

If tan A= cot B. prove that : A+B =90^(@)

If tan A = cot B , prove that A + B = 90^(@) .

If tan A = cot B , prove that A + B= 90 ^@

If tan A = cot B, prove that A + B = 90^@ .

If tan A = cot B, then prove that A + B = 90°.

(tan A) / (1-cot A) + (cot A) / (1-tan A) = 1 + tan A + cot A = 1 + sec A cos ecA (1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

if tan A=cot B then prove that A+B=90^(@)
