Essential Mathematics Formulas

Quadratic Formula
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]
Pythagoras
\[a^2+b^2=c^2\]
Trigonometric Identity
\[\sin^2\theta+\cos^2\theta=1\]
Power Rule
\[\frac{d}{dx}(x^n)=nx^{n-1}\]

Quick Practice with Reveal Answer

Question 1

Find the value of \(x\): \(2x+5=17\)

\[2x=12\Rightarrow x=6\]

Question 2

If \(a=3\) and \(b=4\), find \(\sqrt{a^2+b^2}\).

\[\sqrt{9+16}=\sqrt{25}=5\]
🧮 Interactive Math Tools
