Whats the intergral of sqrt(25-9x^2)?
I would factor out 9 from under the radical to give 1/3*sqrt(25/9 - x^2) and use trig substitution. After I got the antiderivative I might then go to the Wolfram site to check my result against theirs.rochfor1 said:Factor out a 25 from under the radical and use trig substitution.
Nonsense.Mark44 said:BTW, there is no such word as "intergral."
An integral is a mathematical concept that represents the area under a curve in a graph. It is used to calculate the total value of a function over a given interval.
"sqrt" is a mathematical notation that stands for the square root of a number. For example, sqrt(25) equals 5.
To find the integral of a function, you must first determine the antiderivative of the function. Then, you can use the fundamental theorem of calculus to calculate the integral by plugging in the upper and lower limits of the interval.
The integral of sqrt(25-9x^2) can be used to find the area under the curve of the function. It can also be used to find the total value of the function over a given interval.
Yes, there are various methods for solving integrals, such as substitution, integration by parts, and trigonometric substitution. The appropriate method to use depends on the complexity of the function.
