Logarithmic differentiation
To find derivatives of the functions of the form [f(x)]g(x)
Procedure is:
Let y = [f(x)]g(x)
Take logarithms on both sides
Log y = g(x)*log [f(x)]
Differentiate w.r.t. x
(1/y)*dy/dx = g(x)*(1/f(x))*d(f(x))/dx + log [f(x)]*d[g(x)]/dx
Therefore dy/dx = (1/y)*[ g(x)*(1/f(x))*d(f(x))/dx + log [f(x)]*d[g(x)]/dx]

Curve Sketchig - Some Useful Hints
To evaluate the areas of bounded regions, one has to know the rough sketch of the curve.
The principles/ideas that help in visualizing the curve or rough sketching the curve are:
1. Origin and tangents at the origin
Check whether the curve passes through the origin and finding out whether (0,0) satisfies the curve equation.
If the curve passes through (0,0) find the equation of tangent at (0,0)
2. Points of intersection of the curve with the coordinate axes
You can find the point at which the curve crosses the x-axis by putting y = 0 in the curve equation.
Similarly putting x = 0 gives the point at which the curve passes y-axis.
3. Symmetry
If all powers of y in the curve equation are even, then the curve is symmetric about x-axis.
The familiar curve y² = 4ax is symmetric about x-axis.
If all powers x in the equation of curve are even, it is symmetric about y-axis.
If by putting x = -x and y = -y, the equation of the curve remains the same, then it symmetric in opposite directions.
If the equation remains unaltered by interchanging x and y in the equation, then it is symmetric about the line y =x.
4. Regions where the curve does not exist
In the regions where the curve does not exist, x or y values will be imaginary.
In the case of y² = 4ax, when x is negative, y values will be imaginary. Hence curve does not exist on the left side of y-axis.
5. Find points where dy/dx = 0
At these points, the slope of the tangent to the curve is zero and the tangent will be parallel to the x axis.
6. Find maxima and minima points
Find points where dy/dx = 0 and check the sign of d²y/dx² at these points and find out maximum (d²y/dx² is negative) and minimum (d²y/dx² is positive) points of the curve.
Also find the interval in which the dy/dx is g.t. 0. In this interval, the function is monotonically increasing.
In the interval in which dy/dx is l.t. 0, the function is monotonically decreasing.

Coordinates of a point in space
Thee mutually perpendicular lines in space define three mutually perpendicular planes which in turn divide the space into eight parts known as octants and the lines are known as the coordinate axes.
(x,y,z), the coordinates of a point P are the perpendicular distances from P on the three mutually rectangular coordinate planes YOZ, ZOX, and XOY respectively. The coordinates of a point are the distances from the origin of the feet of the perpendiculars from the point on the respective coordinate axes.
Sign convention of three dimensional geometry
All distances measured along OX, OY, and OZ will be positive.
All distances measured along or parallel to OX’, OY’, Oz’ will be negative.

Direction cosines and direction ratios
Direction cosines and direction ratios of a line
The direction cosines of a line: The direction cosines of a line are defined as the direction cosines of any vector whose support is the given line.
If A and B are two points on a given line L, then direction cosines of vectors AB and BA are the direction cosines of line L. If α, β, γ, are the angles which the line L makes with positive directions of x-axis, y-axis, and z-axis respectively, then its direction cosines are either cos α, cos β , cos γ or -cos α, -cos β ,- cos γ.
Therefore if l,m,n are direction cosines of a line, then –l.-m,-n are also its direction cosines.
Also l² +m² + n² = 1
If P and Q are two points with coordinates P(x1,y1,z1) and Q(x2,y2,z2) on line L, it direction cosines (of L or PQ) are

Plane - Definition and Equation
A plane is a surface such that if any two points are taken on it, the line segment joining them lies completely on the surface. It means every point on the line segment joining any two points on the plane lies on the plane.
