Question

(1+tan^2Q) cos^2Q = 1 1st and accurate to answer will be marked as BRAINLIEST!!!!!

Answer 1

Answer:

hey here is your solution

Mark it as brainliest pls

Step-by-step explanation:

so 1+tan square Q=sec square Q

this sec square Q×cos square Q=1

so as sec=1/cos

thus cos square Q and cos square Q gets eliminated

so it is nothing but 1

thus lhs=rhs

thus proved

hope it helped u a lot

Answer 2

Answer:

1

Step-by-step explanation:

(1+tan^2Q)cos^2Q.

: 1+tan^2Q= Sec^2Q

Sec^2Q.Cos^2Q

1/cos^2Q. Cos^2Q
