The radius of a cylinder is increasing at the rate 2 cm/sec and its height is decreasing at the rate 3 cm/sec, then find the rate of change of volume when the radius is 3cm and the height is 5 cm.
In a certain culture of bacteria the rate of increase is proportional to the no.of bacteria present at that instant it is found that there are 10000 bacteria present in 3 hours and 40000 bacteria at the 5 hours the number of bacteria present in the beginning is?
Area of the Region bounded by the curve y=√49-x2 and x-axis is .
∫ (x2 - 1)dx/(x3(2x4 - 2x2 1)1/2) = ?
\(\int \frac{1}{(x + 2)(1 + x)^2} \, dx\)
\(\int \frac{1}{\cos^3 x \sqrt{\sin 2x}} \, dx\)
\( \int \left( \frac{1}{7} - 6x - x^2 \right) \, dx \)
If the line ax+by+c=0 is a normal to the curve xy=1, then
