Mathematics MCQS for class 12 with Answers

The solution of dy/dx = Sin x is ________
y = Sin x + c
y=Cosec x +c
ex Cox + c
y= -SIn x + c

if y =  f(x) be different function then:
ay = f(x + ?x)+ f(x)
?y =  f(x) – f(x +?x)
?y = f(y + ?y) -f(x)
ay = f(x +?) – f(x)

? Cot(ax+b)dx= _________
1/a ln |Sin(ax+b)| + c
1/a ln |Cos(ax+b)|
1/a ln |Cos(ax+b)| + c
1/b ln|Sin(ax+b)|

? Cosec(ax+b)Cot(ax+b)dx= _________
1/a Cot(ax+b)
1/a Sec(ax+b) + c
-1/a Cot(ax+b) + c
-1/a Cosec(ax+b) + c

? ebx+kdx=_________
1/b abx+k lna
1/b abx+k
1/b abx+k ln b
1/blna abx+k + c

If
None of these
Derivative
Differential coefficient
Integral

If y= x2+2xthen dy =
2dx
2(x+1)
2x dy
2x(x-1)dx

? Cosx [lnSinx /Sinx] dx =________
1/2 ln(Sin x)2 + c
(ln Sin x)2 + c
ln (Sin x)2+ c
x Sin x – Cosx + c

5?2 f(x)dx = 8, and 1?2 f(x)dx = 3, then 5?1 f(x)dx =
24
-5
-11
5

If a < c < b then b?a f(x) dx =
a?cf(s)dx
b?c f(x) dx
y = Tan(ex+ c)
c?a f(x) dx
