Question

Plz answer this question it is urgent

Sec^4ø-sec^2ø=tan^2ø+tan^4ø

Answer 1

Step-by-step explanation:

Left side

- sec^4x - sec^2x

= 1/cos^4x - 1/cos^2x

take l.c.m. .....

1 - cos^2x/ cos^ 4x

sin^2x/ cos^4x

tan^2x (1/cos^2x)

now we apply the trig identity ...i.e..

1/cos^2x = (1 + tan^2x )

now....left side is...

tan^2x (1+ tan^2x ) = tan^4x + tan^2x

hence proved.....

thats ur answer....i jst hope that will hlp uhh....

if uh r satisfied with this answer....then mark this as a brainlist .....

thnkew....
