Calculus Help

Calculus is the study of change and it is a vital topic of Mathematics. Integral calculus and differential calculus are two main branches of this topic. Differential calculus is concerned with rates of change whereas integral calculus gives information about the accumulation of quantities. Moreover, these branches are connected with each other in respect of fundamental theorem. It is stated that calculus was founded in the 17th century and since then; its concepts have been applied in many sectors including engineering, science, economics, computer science, medicine and others. Moreover, calculus is referred as the part of modern Mathematics. Students are suggested to learn this topic in a step-by-step manner.

Calculus is quite extensive and it has three parts like ancient, medieval and modern calculus. Limits, derivative applications, solid of revolution are some important sub-topics that students should learn thoroughly to get a thorough understanding in this topic. Some students find calculus tough and in that case, they are suggested to take online calculus help. TutorVista provides constructive and informative sessions for calculus.

Below are some examples based on calculus:

Solved Examples

Question 1: Find the derivative of f(x) = sin x using first principles.
Solution:
 
f(x) = sin x ... (1)

f(x + h) = sin (x + h) .....(2)

Subtract equation (1) from equation (2), we get

f(x + h) - f(x) = sin(x + h) - sin x

= 2 cos ($\frac{2x+h}{2}$) sin ($\frac{h}{2}$)    [ using identity sin A - sin B = 2 cos($\frac{A+B}{2}$) sin ($\frac{A-B}{2}$)

= 2 cos (x + $\frac{h}{2}$) sin ($\frac{h}{2}$)

$\frac{f(x + h) - f(x)}{h}$ = $\frac{1}{h}$ (2 cos (x + $\frac{h}{2}$) sin ($\frac{h}{2}$))

= $\frac{2 cos (x + \frac{h}{2}) sin (\frac{h}{2})}{2 \times \frac{h}{2}}$  [ Because $\frac{sin \frac{h}{2}}{\frac{h}{2}}$ ]

= cos(x + $\frac{h}{2}$)
$\lim_{h\rightarrow0}$ $\frac{f(x + h) - f(x)}{h}$ = $\lim_{h\rightarrow0}$  cos(x + $\frac{h}{2}$)

= cos x

=> Derivative of sin x is cos x.
 

Question 2: Solve $\int$ $\frac{log\ x}{x}$ dx

Solution:
 
Given: $\int$ $\frac{log\ x}{x}$ dx
Substitute log x = t, then $\frac{1}{x}$ dx = dt

Now $\int$ $\frac{log\ x}{x}$ dx = $\int$ t dt = $\frac{t^2}{2}$
After re-substituting the values, we have
$\frac{(log\ x)^2}{2}$
