Question

sin 7theta+ sin5theta/cos 7theta-cos5theta​

Answer 1

$sin \: 7 \: \theta \: = \: 0.1219$

$sin \: 5 \: \theta \: = \: 0.0872$

$\cos \: 7 \: \theta \: = \: 0.9925$

$cos \: 5 \: \theta \: = \: 0.9962$

$Lets \: put \: the \: values$

$0.1219 + \frac{0.0872}{0.9925} - 0.9962$

$After \: simplifying \: we \: get\:your\: answer$
