 Jul2 awarded Curious Mar17 accepted Find m for which $f(x)=\sqrt[3]{2x^2-mx+1}$ is differentiable on $\mathbb{R}$ Mar17 asked Find m for which $f(x)=\sqrt[3]{2x^2-mx+1}$ is differentiable on $\mathbb{R}$ Aug31 awarded Yearling Apr30 accepted Combinatorics problem: form a team of three people with at least one medic, having 5 nurses and 4 medics. Apr30 asked Combinatorics problem: form a team of three people with at least one medic, having 5 nurses and 4 medics. Feb9 awarded Critic Dec1 awarded Commentator Nov22 comment Find x in $4^{\sin^2x}+4^{\cos^2x}=8$ The error in the third line was just a mistake. On paper I wrote correctly. Nov22 accepted Find x in $4^{\sin^2x}+4^{\cos^2x}=8$ Nov22 comment Find x in $4^{\sin^2x}+4^{\cos^2x}=8$ It was a typographical error the third line. I corrected it. However, it doesn't change the rest of the steps because I considered it to be $8\cdot4^{sin^2x}$ Nov22 revised Find x in $4^{\sin^2x}+4^{\cos^2x}=8$ added 6 characters in body Nov22 asked Find x in $4^{\sin^2x}+4^{\cos^2x}=8$ Nov22 accepted Find x: $2^{2x^2}+2^{x^2+2x+2}=2^{4x+5}$ Nov22 asked Find x: $2^{2x^2}+2^{x^2+2x+2}=2^{4x+5}$ Nov11 accepted Determine $z^n+z^{-n}$ if $z+\frac{1}{z}=-2\cos{x}$ Nov3 comment Determine $z^n+z^{-n}$ if $z+\frac{1}{z}=-2\cos{x}$ Yes, x is real. Nov3 asked Determine $z^n+z^{-n}$ if $z+\frac{1}{z}=-2\cos{x}$ Nov3 accepted Solve for $z$ in $4z^2+8|z|^2-3=0$ Nov3 comment Solve for $z$ in $4z^2+8|z|^2-3=0$ So finally it will be $4z^2+8z^2-3=0$? Thank you!
