यदि `cos^(-1)x=2sin^(-1)x` ,तो x बराबर hai -

If 0

If sec 2x = cosec(3x-45^@) , then x is equal to: यदि sec 2x = cosec(3x-45^@) है, तो x किसके बराबर है?

If 0 < cos^-1(x) <1 and 1+sin(cos^(-1)x)+sin^2(cos^(-1)x)+sin^3(cos^(-1)x) + ..... =2 then the value of 12 x^2 is____

Solve the equation sqrt(|sin^(-1)| cos x|| + |cos^(-1)| sin x||) = sin^(-1)|cos x | -cos^(-1)| sin x|, (-pi)/(2) le x le (pi)/(2)

If (1 + sin∅)/(1 - sin∅) = p^2/q^2 , then sec∅ is equal to: यदि (1 + sin∅)/(1 - sin∅) = p^2/q^2 , तो sec∅ बराबर है :

Statement -1: if -1lexle1 then sin^(-1)(-x)=-sin^(-1)x and cos^(-1)(-x)=pi-cos^(-1)x Statement-2: If -1lexlex then cos^(-1)x=2sin^(-1)sqrt((1-x)/(2))= 2cos^(-1)sqrt((1+x)/(2))

Statement -1: if -1lexle1 then sin^(-1)(-x)=-sin^(-1)x and cos^(-1)(-x)=pi-cos^(-1)x Statement-2: If -1lexlex then cos^(-1)x=2sin^(-1)sqrt((1-x)/(2))= 2cos^(-1)sqrt((1+x)/(2))

If sin^(-1)(1-x)-2sin^(-1)x=cos^(-1)x , then x=

If roots of x^2- 4x + a = 0 are equal, then a = यदि x^2- 4x + a = 0 के मूल बराबर है, तो a = ?
