`lim_(x=0) {sinh3x+a_1 sinh2x+a_2 sinhx}/x^5` have a finite limit find and determine the necessary values of `a_1 & a_2`

lim_(x=0)(sinh3x+a_(1)sinh2x+a_(2)sinh x)/(x^(5)) have a finite limit find and determine the necessary values of a_(1)&a_(2)

If sinhx=(1)/(2) find cosh2x+sinh2x

IF sinhx= 3//4 then find cosh2x and sinh2x.

sinhx=3//4 " then find" cosh2x and sinh2x.

If sinhx = 3/4 then find cosh 2x and sinh 2x .

If cosx=a_0+a_1 x+a_2x^2+... then the value of a_2 is

If a_1 and a_2 are two non-collinear unit vectors and if |a_1+a_2|=sqrt(3) , then the value of (a_1-a_2)*(2a_1+a_2) is

If cos4x=a_0+a_1cos^2x+a^2cos^4x is true for all values of x in R , then the value of 5a_0+a_1+a_2 is_______

If cos4x=a_0+a_1cos^2x+a^2cos^4x is true for all values of x in R , then the value of 5a_0+a_1+a_2 is_______
