Proove that <br>1/1-sin theta + 1/1+cos theta = 2×sec square theta ​
Rina8888 [55]

Step-by-step explanation:

We need to prove that,

\dfrac{1}{1-\sin\theta}+\dfrac{1}{1+\sin\theta}=2\times \sec^2\theta

Taking LHS,

\dfrac{1}{1-\sin\theta}+\dfrac{1}{1+\sin\theta}\\\\=\dfrac{(1+\sin\theta)+(1-\sin\theta)}{(1-\sin\theta)(1+\sin\theta)}\\\\=\dfrac{2}{1-\sin^2\theta}\\\\\text{As}\ 1-\sin^2\theta=\cos^2\theta\\\\=\dfrac{2}{\cos^2\theta}\\\\\text{As}\ \dfrac{1}{\cos^2\theta}=\sec^2\theta\\\\=2\sec^2\theta\\\\=RHS

Hence, LHS = RHS.

The sum of two numbers is 14. When one number is added to twice the other number, the result is 25. Find the numbers
ELEN [110]

Let x and y be the two numbers. We have:

\begin{cases}x+y=14\\x+2y=25\end{cases}

Subtract the first equation from the second to get

y=11

And deduce

x+11=14 \iff x=3

The two numbers are 3 and 11.
