Question

tan theta - tan(90° - theta) = 0, find the value of theta​

Answer 1

$\huge\sf\red{ANSWER}$

$\tan(90 - θ) \\ = \cot(θ) </p><p></p><p>and tanθ \: ⋅cotθ</p><p></p><p>=tanθ \: ×1 \div \tanθ</p><p> </p><p> = 1</p><p></p><p></p><p></p><p></p><p>$

Answer 2

Step-by-step explanation:

We know that, Tan(-θ) = -tanθ. So, we can write eqn1 as: -tan(90-θ) which finally gives you -cotθ.
