newton
A really micro micro-service for advanced math.
Newton does anything from numerical calculation to symbolic math parsing.
How does it work?
- Send a GET request to newton with a url-encoded math expression and your preferred operation.
- Get back a JSON response with your problem solved.
Show me
Let's find the derivative of x^2. So, we send a request to the newton url saying just that:
-> https://newton.now.sh/api/v2/derive/x%5E2 (Note the url-encoded ^)
Now, we get the following response:
{
"operation":"derive",
"expression":"x^2",
"result":"2 x"
}
It's that simple!
Get Started
- Send a GET request to newton.
https://newton.now.sh/api/v2/:operation/:expression
Note: :operation is the math operation that you want to perform. :expression is the url-encoded math expression on which you want to operate. View available operation endpoints below!
- That's it! You'll be returned a JSON object with the operation you requested, the expression you provided, and the result of the operation performed on the expression.
View available endpoints:
| Operation | API Endpoint | Result |
|---|---|---|
| Simplify | /simplify/2^2+2(2) | 8 |
| Factor | /factor/x^2 + 2x | x (x + 2) |
| Derive | /derive/x^2+2x | 2 x + 2 |
| Integrate | /integrate/x^2+2x | 1/3 x^3 + x^2 + C |
| Find 0's | /zeroes/x^2+2x | [-2, 0] |
| Find Tangent | /tangent/2lx^3 | 12 x + -16 |
| Area Under Curve | /area/2:4lx^3 | 60 |
| Cosine | /cos/pi | -1 |
| Sine | /sin/0 | 0 |
| Tangent | /tan/0 | 0 |
| Inverse Cosine | /arccos/1 | 0 |
| Inverse Sine | /arcsin/0 | 0 |
| Inverse Tangent | /arctan/0 | 0 |
| Absolute Value | /abs/-1 | 1 |
| Logarithm | /log/2l8 | 3 |
Keep in mind: To find the tangent line of a function at a certain x value, send the request as c|f(x) where c is the given x value and f(x) is the function expression, the separator is a vertical bar '|'. See the table above for an example request.
To find the area under a function, send the request as c:d|f(x) where c is the starting x value, d is the ending x value, and f(x) is the function under which you want the curve between the two x values.
To compute fractions, enter expressions as numerator(over)denominator. For example, to process 2/4 you must send in your expression as 2(over)4. The result expression will be in standard math notation (1/2, 3/4).
