Just try fittin in iota in your calculus equations.

eg. x^2 = - (ix)^2

you can then use e^i@ = cos(@) + i sin(@)

formula to find the answer.

try it this idea is a serious whirlwind.

## Yes I Am An Indian

Yes i am saying it makes problemz simpler, you can also use it if u dont remember a formula etc.

for example (let | be the integration sign)

| root of(a^2 - x^2) dx = | root of(x^2 + a^2) dx

this worx as i is not dependent on x

but is i a const?

which is**false**even if we throw in a random $\displaystyle \pm$ sign or two
