Solved] tan(90-A)=?

Solved 21 If tan a= 90°

I. 1. Find sin 0, cos 0 and tan (90° - 0).AC=34 (hypo)BC=30AB

Trigonometrical Ratios Table, Trigonometric Standard Angles

Prove that tanA tan(90 - A) = cotA cot(90 - A) = sinA sec(90 - A

So this is apparently scartch's answer to tan(90) : r/scratch

cot A + tan (180^@-A) + tan (90^@ + A) + tan (360^@ + A) =0

Solution: If x+y=90, find (sinxtany)/(tanxsiny)

SOLVED: Simplify the expression : (sin(90°-×)/(tan(90°-x)) cos x

Prove that cos( 90-a)sin(90-a)/tan(90-a)=1-cos2a

Question 5 - Solve tan 2x = - cot (x+pi/3) - Teachoo - Examples
