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

Alla [95]

$\frac{1+cos\alpha}{sin\alpha}+\frac{sin\alpha}{1+cos\alpha}=2cosec\alpha\\\\L=\frac{(1+cos\alpha)(1+cos\alpha)+sin\alpha\cdot sin\alpha}{sin\alpha(1+cos\alpha)}=\frac{1+2cos\alpha+cos^2\alpha+sin^2\alpha}{sin\alpha(1+cos\alpha)}\\\\=\frac{1+2cos\alpha+1}{sin\alpha(1+cos\alpha)}=\frac{2+2cos\alpha}{sin\alpha(1+cos\alpha)}=\frac{2(1+cos\alpha)}{sin\alpha(1+cos\alpha)}\\\\=\frac{2}{sin\alpha}=2\cdot\frac{1}{sin\alpha}=2cosec\alpha=R$

Find Four constructive odd integers whose sum is 224 what is the largest number

rusak2 [61]

Answer:

53, 55, 57, and 59

Step-by-step explanation:

Let the numbers be

x, x +2, x +4, and x+6. Then

x + x+2 + x +4 + x + 6 = 224 Combine like terms

4x + 12 = 224 Subtract 12 from each side

4x = 212 Divide each side by 4

x = 53

The four consecutive integers are 53, 55, 57, and 59.

<em>Check: </em>

53 + 55 + 57 + 59 =224
