Take MCQ Maths Test1.
If tanθ+sinθ=P; tanθ-sinθ=q P.T P2-q2=4\(\sqrt{pq}\)
2.
If 15tan2 θ+4 sec2 θ=23 then find the value of (secθ+cosecθ)2 -sin2 θ
3.
If ATB=90o then prove that
\(\sqrt { \frac { tanA\quad tanB+tanA\quad cotB }{ sinA\quad secB } } -\frac { { Sin }^{ 2 }A }{ { Cos }^{ 2 }A } =tanA\)
4.
Express cot 85° + cos 75° in terms of trigonometric ratios of angles between 0° and 45°.
5.
Evaluate \(\frac { tan{ 65 }^{ o } }{ tan{ 25 }^{ o } } \)

cot 85° + cos 75°
= cot(90° - 5°) + cos(90° - 15°)
= tan 5° + sin 15°
5.
We know:
cot A = tan(90o - A)
So,
cot 25° = tan (90° - 25°) = tan 65°
\(\frac { tan{ 65 }^{ o } }{ tan{ 25 }^{ o } } \) = \(\frac { tan{ 65 }^{ o } }{ tan{ 25 }^{ o } } \) = 1
