Verify the identity 6cos^2(x) -3 = 3 - 6sin^2(x)

Mathematics
1 answer:
Lorico [155]3 years ago
5 0

Answer:

It is proved that  6\cos ^{2}x -3 = 3 - 6\sin ^{2} x .

Step-by-step explanation:

We already have the identity of x as \sin ^{2}x + \cos ^{2}x = 1 .......... (1)  .

So, from equation (1) we can write that

\cos ^{2} x = 1 - \sin ^{2} x

⇒ 6\cos ^{2} x = 6 - 6 \sin ^{2} x

⇒ 6\cos ^{2} x -3 = 6 - 6 \sin ^{2}x -3

⇒ 6\cos ^{2}x -3 = 3 - 6\sin ^{2} x

Hence, it is proved that  6\cos ^{2}x -3 = 3 - 6\sin ^{2} x . (Answer)

Evaluate \dfrac j4 4 j ? start fraction, j, divided by, 4, end fraction when j=12j=12j, equals, 12.
cricket20 [7]

We need to evaluate the value of fraction \frac{j}{4}.

We also given j=12.

In order to evaluate the value of fraction \frac{j}{4}, we need to plug j=12.

Plugging j=12, we get

\frac{j}{4}= \frac{12}{4}

We have 12 in numerator and 4 in denominator.

We always divide top number by bottom number.

So, we need to divide 12 by 4.

On dividing 12 by 4 we get 3.

<h3>Therefore, \frac{j}{4} = 3.</h3>

To calculate a fraction of a quantity, multiply the quantity by the numerator of the fraction and divide by the denominator

\frac{3}{4} of 20 = (3 × 20 )/4 = \frac{60}{4} = 15

\frac{3}{5} of 20 = (3 × 20 )/5 = \frac{60}{5} = 12
