Question

Quizplus · Accepted Answer

In quadrant II, cosine is negative and sine is positive, so their product $\cos t \sin t$ is negative. Additionally, the reciprocal of cosine, secant, is also negative in quadrant II. Therefore, the sign of $\cos t \sin t$ is negative and the sign of secant is also negative, leading to choice C as the best answer.
