Mathematics MCQS for class 12 with Answers
The solution of differential equation dy/dx = 1/?x2-1 is:
cot hx + c
y = cosh-1x + c
y = sinh-1 x+c
y = tanh-1x+ c
Substitution for the integrals involving the expression ?a2-x can be:
x = a sin?
x =a cosec?
x = a tan?
x = a cot?
-? ecotx-1/1+x2 dx =
esecx + c
