" If "sin x+cos x=(1)/(5)," then "tan2x" is "

If sin x+cos x=(1)/(5), then tan 2x is

If sin x + cos x = 1/5 , then tan 2x is .............. A) 25/17 B) 7/26 C) 25/7 D) pm24/7

if sin x+cos x=(1)/(5), then find the value of tan2x.

If (sin x + cos x)/(sin x - cos x) = (6)/(5) , then the value of (tan^(2) x + 1)/(tan^(2) x-1) is :

If 3sin x+4cos x=5, then 6(tan)(x)/(2)-9(sin)^(2)(x)/(2)=

Prove the following: ("sin" 5x-2 sin 3x+"sin" x)/(cos 5x-cos x)="tan" x .

" If "I=int(cos^(3)xdx)/((sin^(4)x+3sin^(2)x+1)tan^(-1)(sin x+cos ecx)),=-A log|tan^(-1)(sin x+cos ecx)|+C" ,then A is equal "
