\(\color {magenta}\frac{1\times1.4}{2}\color{black}=\color{cyan}1\times0.7\color{black}=\color{magenta}\textbf{0.7}cm^2\)

\(\color{blue}\textbf{I am using} \color{blue }\LaTeX\)

I am so happy about knowing I can use colors in LaTeX so I am too happy to show off XD

Or do you mean the percentage increase which has similar meaning as 'increasing rate'?

(29209-8904)/8904 x 100%

\(\approx \) 228%

\(\frac{2}{3}\times \frac{3}{4}\)

=\(\frac{2\times3}{3\times4}\)

\(\frac{6}{12}\)

=\(1\over2\)

Use sine law and cosine law.

20/15 = 4/3

Just think about it, how can you divide 3 cookies to 0 friends?

\(-\frac{5}{6}:\frac{5}{12}= -10:5=-2:1\)

sin 1° = 0.01745.......

sin 1 radians = 0.8415......
