The last virtual office hour! (Chegg Trig & Precalculus)Which equation has no real solution: e^x=2, e^e^x=2, or e^e^e^x=2?how is e^e^x=1 solvable??Ultimate Trig Identity Study GuideYou dont need calculus for this questionLimit of x^(y^z) as (x, y, z) goes to (0, 0, 0)Can f(x)=f^-1(x)?solving x^x=1 but x is not real!A lovely calculus proof problem! (National Taiwan University entrance exam)I finally took the limit of the quadratic formulaLive: This is what the 2023 Berkeley Math Tournament calculus test looks like!100 precalculus equations
