A ratio is used to describe how two or more quantities are related. For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:6. This means that for every 2 scoops sugar crystals, there will need to be 6 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 600 ounces of water.

Show tan (x) + cot (x) • sec(x)
topjm [15]
\tan x+\cot x=\csc x.\sec x

Let us change tan x and cot x to sin x and cos x

\begin{gathered} \because\tan x=\frac{\sin x}{\cos x} \\ \because\cot x=\frac{\cos x}{\sin x} \end{gathered}

Substitute them on the left side

LHS=\frac{\sin x}{\cos x}+\frac{\cos x}{\sin x}=\frac{\sin^2x+cox^2x}{\cos x\sin x}

I multiplied the denominators and multiply each numerator by the opposite denominator

\because\sin ^2x+cox^2x=1\therefore L.H.S=\frac{1}{\sin x\cos x}

Now we will work on the right hand side

\begin{gathered} \because\csc x=\frac{1}{\sin x} \\ \because\sec x=\frac{1}{\cos x} \end{gathered}

Substitute them on the right side

\because R.H.S=\frac{1}{\sin x}\times\frac{1}{\cos x}=\frac{1}{\sin x\cos x}

The L.H.S = R.H.S = 1/(sin x cos x)
