Answer:
0°
Step-by-step explanation:
break tan theta and cot theta into sin theta and cos theta . put sec theta =1/ cos theta and cosec theta = 1/ sin theta
simplify it as shown in photo.
now put sin^ 4 theta and cos^ 4 theta and 4 sin^2 theta cos^2 theta together as (cos^2 theta + sin ^ 2 theta )^2 .
furthermore put cos^2 theta - sin^ 2 theta as cos2 theta
you will get cos 2 theta as 1 therefore theta =0°
