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 $\frac{1}{sin}=cosec\\$

<em>Finally </em> $2cosecA$ <em />

The first answer already given, what's the second answer (in the green box)

chubhunter [2.5K]

Solution:

Since the graph passes through the given points, (7, 20) & (-2, 11) are the solutions of the given equation <em>y = x + ?</em>.

⇒<em>(x, y)</em> = (7, 20); (-2, 11)

Substituting the variables with (7, 20),

20 = 7 + <em>?</em>

20 - 7 = <em>?</em>

<em>?</em> = 13

Similarly,

11 = -2 + <em>?</em>

<em>?</em> = 13

∴ <em>y</em> = 13
