Simple and easy to use calculator. Just input the expression you want to calculate.
Available functions:
• sin(arg) cos(arg) tan(arg) ctg(arg)
• pow(base, exponent) = base^exponent
pow(base) = pow(base, 2)
• sqrt(degree, radicand) = degree^(1/radicand)
sqrt(radicand) = sqrt(2, radicand)
• log(base, power)
log(power) = log(10, power)
ln(power) = log(e, power)
• ANS
