If `sin A=(3)/(4)`,calculate `cosA` and `tan A`

If sin A=3/4 , calculate cos A and tan A.

If sin A=(3)/(5) , prove that tanA+(1)/(cosA)=2 or -2

If sin A=a cos B and cosA=b sinB then, (a^2 - 1) tan^2 A+(1 -b^2)tan^2B is equal to

Prove that : (sin 5theta + sin 3theta)/(cos 5theta + cos 3theta) = tan 4theta

In a Delta ABC , if cosA cos B cos C= (sqrt3-1)/(8) and sin A sin B sin C= (3+ sqrt3)/(8) , then The value of tan A + tan B + tan C is

In a Delta ABC , if cosA cos B cos C= (sqrt3-1)/(8) and sin A sin B sin C= (3+ sqrt3)/(8) , then The value of tan A tan B tanC is

i) If sinA+sinB=sqrt(3)(cosB-cosA) , prove that: sin3A+sin3B=0 ii) If A,B and C are in arithmetic progression, then prove that: cotB=(sinA-sinc)/(cosC-cosA)

In a right - angled triangle , it is given that A is an acute angle and tan A=5/12 (cosA+sinA)/(cosA-sinA)

If 3 sin A = 4 cos A , find the value of : tan^2A-sec^2A

If secA=5/4 , verify that (3sinA-4sin^3A)/(4cos^3A-3cosA)=(3tanA-tan^3A)/(1-3tan^2A)
