If A and B are acute angles such that tanA=cotB , then show that A+B =90^(@) .

If A and B are acute angles such that tanA=cotB , then show that A+B =90^(@) .

If tanA=cotB, prove that A+B= 90^@ .

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

Assertion (A) : tan 70^(@) - tan 20^(@) = 2 cot 40^(@) Reason (R ) : If A + B = 90^(@) then tan A. tan B = 1

If tanA=cotB,prove that A+B=90^@

सिद्ध कीजिए कि |vecA xx vecB|^(2) + |vecA * vecB|^(2) = (AB)^(2).
