Verify:<br>cos(2A)=(cotA-tanA)/cscAsecA

kolbaska11 [484]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

cot A = $\frac{cosA}{sinA}$ , tanA = $\frac{sinA}{cosA}$ , cscA = $\frac{1}{sinA}$ , secA = $\frac{1}{cosA}$

Consider the right side

$\frac{cotA-tanA}{cscAsecA}$

= $\frac{\frac{cosA}{sinA}-\frac{sinA}{cosA} }{\frac{1}{sinA}.\frac{1}{cosA} }$

= $\frac{\frac{cos^2A-sin^2A}{sinAcosA} }{\frac{1}{sinAcosA} }$

= $\frac{cos^2A-sin^2A}{sinAcosA}$ × sinAcosA ( cancel sinAcosA )

= cos²A - sin²A

= cos2A

= left side ⇒ verified

Guys plsss i need help. It needs work too

Ghella [55]

Answer:

$f(x+h)=x^2+2xh+h^2+2x+2h$

Option D is correct option.

Step-by-step explanation:

We are given: $f(x)=x^2+2x$

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

$f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h$

Finding f(x+h) we get:

$f(x+h)=x^2+2xh+h^2+2x+2h$

Option D is correct option.
