Question

one plus 10 squared theta is equal to how

Answer 1

HEY MATE......
_________
IT IS A TRIGONOMETRY IDENTITY:

1+ tan^2 theta= sec^2 theta.

Answer 2

1 + tan²theta = sec²theta

CORRECT QUESTION:-

one plus tan squared theta equal to what

ANSWER:-

GIVEN:- One plus Tan squared theta

TO FIND:- answer

SOLUTION:-

One plus tan squared theta = 1 + tan²theta

$1+tan^20=sec^2 0 \\ tan 0=sin 0/cos 0 \\ sec 0=1/cos 0 \\ 1+sin^20/cos^20 = 1/cos^20 \\ cos^20+sin^20 /sin^20 = 1/cos^20$

As we know,

$1/cos^20 = sec^20$

Hence proved 1 + tan²theta = sec²theta
