NOTE : This calculator does not support associate operations. E.g 2(4-3) will give NaN as result, rather users should input the above expression like this 2*(4-3) to get a valid result. The support for associative operations will be added in the upgraded version.

OPERATIONS / FUNCTIONS SUPPORTED ARE :
Simple expressions
Simple calculation
Changing expression string
Using operators
Power function
Using numbers in scientific notation
Evaluating relations
Using built-in functions
Unary function e.g sin(2)-cos(3)
Binary Function e.g min(3,4) + max(-2,-1)
Function with 3 arguments e.g if(3<2, 1, if(1=1, 5, 0) )
User defined arguments
Summation & Product iterated operators
SIGMA summation operator e.g: sum(i, 1, 10, 2*i) , e.g: sum(i, 1, 10, i, 0.5).
PI product operator e.g: prod(i, 1, 5, i)
Derivatives e.g: cos(1) - der(sin(x), x, 1) e.g: cos(1) - der( sum(k,0,10,(-1)^k*(x^(2*k+1))/(2*k+1)!), x, 1
Integration : e.g 2 * int( sqrt(1-x^2), x, -1, 1 )
Built-in constants e.g: pi+e e,g: ( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 )
Using built-in constants
Solving equations
Examples:
solve( 2*x - 4, x, 0, 10 )
solve( cos(x), x, 0, pi )
solve( cos(x), x, -pi, pi )
y = 4, solve( x-y, x, 0, 10 )", y
Solving Quadratic Equations e.g x^2 + 5x+ 2
etc.
