Question

5sin theta -12cos theta

Answer 1

$\huge{\mathfrak{SOLUTION}}$

Given = 5sinФ-12cosФ=0

>> 5sinФ = 12cosФ

>> $\frac{5}{12}$ = $\frac{cosФ}{sinФ}$

>>$\frac{5}{12}$ = cotФ

>> Adjacent - 5

>> Opposite - 12

>> Hypotenuse - √12²+5² = 13

Hence secФ = $\frac{13}{5}$

and cosecФ = $\frac{13}{12}$
