Question

NEED HELP ASAP!!!! Simplify the expression. sin^2 Ф/csc Ф tan^2 Ф

A. sin^2 Ф

B. sin Ф cos^2 Ф

C. sec^2 Ф

D. csc Ф

Answer 1

Answer:

Option B: sin Ф cos² Ф

Step-by-step explanation:

Given expression:

$\frac{sin^2 \phi}{csc \ \phi \ * tan^2 \ \phi} = \frac{sin^2 \phi}{\frac{1}{sin \ \phi}*\frac{sin^2 \phi}{cos^2 \phi}  } = sin \ \phi * cos^2 \ \phi$

Note:

csc Ф = 1/sin Ф

tan Ф = (sin Ф)/(cos Ф)
