When using integration by parts it must have at least two functions, however this has only one function: Put x = s i n 2 t. I = ∫ t 2 cos t dt.

Integration of sin inverse x ka whole square table of integrals (math | calculus | integrals | table of) power of x.
To evaluate this integral we first use the method of substitution and then we use integration by parts.
Z = x, by differentiation cos. To determine the integration of sin inverse x, we will substitute x with sin θ. Dx = 2 sin t cos t dt. Integration of sin inverse x.
The integral of inverse sine squared is of the form.
By using integration by parts formula, i = t cos t + ∫ 1. We have, i = ∫ c o s − 1 x dx. 142 dx x ³ 2. 22 1 arctan du u c a u a a ³ 3.

Where c is the integration constant.
The integral of x sine inverse of x is of the form. Ex 7.6, 10 (sin^(−1)𝑥 )^2 ∫1 (sin^(−1)𝑥 )^2 𝑑𝑥 let sin^(−1)𝑥=𝜃 ∴ 𝑥=sin𝜃 differentiating both sides 𝑤.𝑟.𝑡.𝑥 𝑑𝑥/𝑑𝜃=cos𝜃 𝑑𝑥=cos𝜃.𝑑𝜃 thus, our equation becomes ∫1 (sin^(−1)𝑥 )^2 𝑑𝑥 = ∫1 𝜃^2. Ex 7.6, 7 (method 1) 𝑥 sin^ (−1)𝑥 ∫1 〖𝑥 〖𝑠𝑖𝑛〗^ (−1) 〗 𝑥 𝑑𝑥 let x = sin𝜃 dx = cos𝜃 𝑑𝜃 substituting values, we get ∫1 〖𝑥 〖𝑠𝑖𝑛〗^ (−1) 〗 𝑥 𝑑𝑥 = ∫1 〖sin𝜃 〖𝒔𝒊𝒏〗^ (−𝟏) (𝒔𝒊𝒏𝜽 ) cos𝜃 𝑑𝜃 〗 = ∫1 〖sin𝜃 𝜽 cos𝜃 𝑑𝜃 〗 = 1/2 ∫1 〖𝜃 〖 (2 sin〗𝜃 cos〖𝜃)〗 𝑑𝜃 〗 = 1/2 ∫1 〖〖𝜃 sin. ∴ i = ∫ ( s i n − 1 x) 2 dx.

Let’s start by showing you how we can use the integral formula and return a sine inverse function when integrated. We will use the following formulas to determine the integral of sin inverse: We have, i = ( s i n − 1 x) 2 dx. The integration of sine inverse is of the form.
∴ i = ∫ c o s − 1 x dx.
When using integration by parts it must have at least two functions, however this has only one function: What is the derivative of sin inverse x? We shall find the integration of cosine inverse by using the integration by parts method. Let s i n − 1 x = t, then, x = sin t dx = cos t dt.
