Question

Prove that is sin power 6 theta + cos power 6 theta + 3 sin squared theta cos square theta is equal to 1

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

(Sin^2)^3+(cos^2)3+3sin^2cos^2=1

(Sin^2+cos^2)(sin^4+cos^4+sin^2+cos^2)+3sin^2cos^2

1×{(sin^2)^2+(cos^2)^2(-sin^2cos^2+3sin^2cos^2)

{(Sin)^2+(cos)^2-sin^2cos^2)+3sin^2cos^2

(Sin^2+cos^2)^2-2sin^2cos^2-sin^2cos^2+3sin^2+cos^2

1=1
