Question

Why Tan²¤ + 1 = Sec²¤​

Answer 1

Here Is Your Ans

____

BY Pythagoras Theorem

h² = p² + b² ---- 1

Divide b² In equation 1

$= > \frac{ {h}^{2} }{b} = \frac{ {p}^{2} }{ {b}^{2} } + \frac{ {b}^{2} }{ {b}^{2} } \\ \\ = > {( \frac{h}{b} )}^{2} = {( \frac{p}{b} )}^{2} + {( \frac{b}{b} )}^{2}$

=> Sec²¤ = Tan²¤ + 1
