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

How Do I Solve 3/2y= 16/y+2

IceJOKER [234]

$\frac{3}{2y}=\frac{16}{y+2}\ \ \ \ \ \ |cross\ multiply\\\\16\times2y=3(y+2)\\\\32y=3y+6\ \ \ \ \ |subtract\ 3y\ from\ both\ sides\\\\29y=6\ \ \ \ \ \ \ |divide\ both\ sides\ by\ 29\\\\\boxed{y=\frac{6}{29}}$

5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

Vinvika [58]

5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2

16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:

Multiply the numbers 16 x 2

16 x 2 = 32

Now multiply the numbers 4 x 2

4 x 2 = 8

Now Multiply the numbers 4 x 2 again

4 x 2 = 8

= 32xy - 8x- 8y

Factor 8 from the expression

Final Answer:
8(4xy-x-y)

I’m not really sure about my answer but i hope it helps!
Sorry if its wrong..
Stay Safe guys!
