Introduction to...

If $$ 3\cos\theta =2\sin\theta $$, then the value of $$ \dfrac{4\sin\theta -3\cos\theta }{2\sin\theta +6\cos\theta }$$ is:

If $$\tan A =\cfrac{5}{12}$$, find the value of $$(\sin A+ \cos A) \times \sec A$$:

The value of tan$$1^{\circ}.tan2^{\circ}.tan3^{\circ}.......... tan89^{\circ}$$ is :

If sin$$\Theta$$  = cos$$\Theta$$, then the value of $$\Theta$$ is :

Simplify:$$\displaystyle \dfrac {\cos 60^0+\sin 60^0}{\cos 60^0-\sin 60^0}$$

The value of $$\cos 1^o.\cos 2^o.\cos 3^o.....\cos 179^o$$ is equal to 

The value of 

$$\tan 9^o\times \tan 27^o\times \tan 63^o\times \tan 81^o=$$

Which one of the following is correct ?

If $$\tan30^0=x, \tan 45^0=y, \tan 60^0=z,$$ then which of the following is/are correct?
