Let E1, E2, E3, …………. En mutually exclusive and exhaustive events and A is dependent event occurs after E1, E2, E3, …………. En. Probability of event A By multiplication theorem . Where stands for...

If the elements of any one row or any one column are variable and rest are constant, then only we apply this formula. Otherwise, we have to expand the determinants and then integrate.

No need to expand the determinants while differentiating. The formula to find the derivative of determinants is given below:

The tangent of angle of the line with the x – axis in anticlockwise direction is called slope of the line. It is denoted by m. Slope of the line AB, Example 1:...
