Question

If tan = 1, find the value of co^2 - sin^2​

Answer 1

Answer:

0

Step-by-step explanation:

Tan θ = 1  => θ = 45°

cos²45 - sin²45 = (1/√2)² - (1/√2)² = 0

Answer 2

Answer:

here your answer.....

0

Step-by-step explanation:

atq

tanx=1

tanx=tan45°

x=45°

now

cos^2x-sin^2x

cos^2[45°]-sin^2[45°]

(1/√2)^2-(1/√2)^2

1/4-1/4=0
