For an easy answer and to be able to answer these problems on your own, I recommend using Desmos. It is a graphing calculator website and all you have to do is type in both sides of the equation in different cells and it will give you the exact point that they cross. Your answer will be the first number in the ordered pair. I hope this helps you with your current and future problems. There is also a testing version of Desmos that you might use during a state test eventually.

Prove that : sinA/1+cosA + 1+cosA/sinA=2cosecA

tekilochka [14]

Step-by-step explanation:

$\frac{sinA}{1+cosA} +\frac{1+cos}{sinA} =2cosec\\\\\\\frac{sin^{2}A+(1+cos)^{2} }{sinA(1+cosA)} \\\\$

$\frac{sin^{2}A+1+cos^{2}+2cos}{sinA(1+cosA)} \\\\$ and we have $sin^{2}+cos^{2} =1$

so $\frac{1+1+2cosA }{sinA(1+cosA)} \\\\$

$\frac{2+2cosA }{sinA(1+cosA)} \\\\$

$\frac{2(1+cosA)}{sinA(1+cosA)} \\\\$

$\frac{2}{sinA}$ we have $\frac{1}{sin}=cosec\\$

Finally $2cosecA$

I really hope this helps coz it took much time

The power of 10 chart

TEA [102]

When you have powers of 10, the number is always 1 followed by how ever many zeros. So, in this case, 10 to the 4th power is 1 followed by 4 zeros, which is 10,000
