Eliminate 'a' and 'b' from :
`y=a cos x+b sin x`

Form a differential equation representing the given family of curves by eliminating arbitrary constants a and b.y = ex (a cos x + b sin x)

Eliminate x from equations sin(a+x)=2b and sin(a-x)=2c .

The differential equation for which y=a cos x+b sin x is a solution is

Eliminate theta from a sin theta + bcos theta = x "and" a cos theta -b sin theta = y

Differentiate w.r.t. x the function cos (a cos x+ b sin x) , for some constant a and b.

The differential equation obtained by eliminating the arbitrary constants a and b from xy = ae^(x) + be^(-x) is

x=a cos t, y=b sin t find dy/dx

Eliminate theta from the following equation : x cos theta - y sin theta = a, x sin theta + y cos theta = b

Eliminate theta from the following equation : x=h+a cos theta, y=k + b sin theta

If x , y in R , then the determinant = |(cos x , -sin x,1),(sin x, cos x,1),(cos(x+y), -sin(x+y), 0)| lies in the interval (a) [-sqrt(2),sqrt(2)] (b) [-1,1] (c) [-sqrt(2),1] (d) [-1,-sqrt(2)]
