(PLEASE HELP) A student claims that sin^2θ + cos^2θ = 1 can only be written one other way. First, decide if the student is correct. Next, justify your decision by either providing an example that supports or disproves the student's claim.

A. The student is correct. The identity can only be rewritten as cos^2θ = 1 - sin^2θ

B. The student is correct. The identity can only be rewritten as cos^2θ = 1 - cos^2θ.

C. The student is correct. The identity can only be rewritten as sin^2θ = 1 -cos^2θ and cos^2θ = 1 - sin^2θ.

D. The student is correct. The identity can only be rewritten as sin^2θ = 1 - cos^2θ and sin^2θ = 1 - sin^2θ.
