Question

Cos^2(48)+cos^(12) pls solve that

Answer 1

Answer:

Step-by-step explanation:

Cos^2(48)+cos^12

=Sin^2(12)+cos^(12). {Cos(90-theta)=sin(theta)}

=1. {sin^2theta + cos^2theta =1}

Answer 2

Answer:1

Step-by-step explanation: cos^2 (48)+cos (60°-48)

cos^2 (48)+sin^2 (12)

sin^2 (theta)+cos^2 (theta)=1
