Question

Determine whether the equation is correct by evaluating each side. Do not use a calculator. Note: Notation such as

\sin ^ { 2 } \theta

stands for

( \sin \theta ) ^ { 2 }

.

1 - \tan ^ { 2 } 60 ^ { \circ } = \sec ^ { 2 } 60 ^ { \circ }

Quizplus · Accepted Answer

The correct identity is $1 + \tan^2 \theta = \sec^2 \theta$, not $1 - \tan^2 \theta = \sec^2 \theta$.
