How to use the constant e?
显示 更早的评论
So the question is given x =0.2 calculate (x^2) *e^4. I know for pi you just type pi which is just pi in the command. But how do I type e in the command window. Also how to use exponents? Do you just go (x^2) ? Do I need those brackets?

exp()=e^
x1 = exp(1j*8*pi/7)

Use exp(). It's the same answer that's already been demonstrated several times on this page.

Use the exponential function exp(y) to compute e^y. For example:
x = 0.2;
Result = (x^2)*exp(4)
Result =

e=exp
then use bracket
i.e. e^5=exp(5) in matlab

say i needed Vout = VS (1 − e^-T/RC) , how would i write this as ive tried exp(-T/R*C) but wouldt work as theres a negative

T = 2;
R = 5;
C = 7;
y = exp(-T/R*C)
z = exp(-14/5)
Or did you want to divide by the product of R and C?
w = exp(-T/(R*C))
q = exp(-2/35)
