By the fundamental theorem of calculus,

[tex]\displaystyle\int_1^2f(x)\,\mathrm dx=\sin\dfrac1{2^2+1}-\sin\dfrac1{1^2+1}[/tex]

The derivative is calculated as -0.19865.

Antiderivatives

It is opposite to the derivative.

Derivative

The rate of change of a function with respect to a variable.

Given

[tex]\rm Antiderivative=sin\dfrac{1}{x^{2} +1} [/tex]

How to calculate the antiderivative?

[tex]\int\limits^2_1 {f(x)} \, dx = sin\dfrac{1}{2^{2} +1} - sin\dfrac{1}{1^{2} +1} \\ \int\limits^2_1 {f(x)} \, dx = sin\dfrac{1}{5} - sin\dfrac{1}{2}\\ \int\limits^2_1 {f(x)} \, dx = 0.19866-0.47942\\ \int\limits^2_1 {f(x)} \, dx = -0.19865[/tex]

Thus, the derivative is calculated as -0.19865.
