Find sin3A, cos<br> 3A and tan 3A when sin=1/2<br>

Slav-nsk [51]

Answer:

Sin 3A = 1

cos 3A = 0

tan 3 A = undefined

Step-by-step explanation:

$\sin A = \frac{1}{2} \\ \therefore \: \sin A = \sin \: 30 \degree.. \bigg( \because \: \sin \: 30 \degree = \frac{1}{2} \bigg) \\ \therefore \: A = 30 \degree \\ \\ now \\ \sin 3A =\sin (3 \times 30 \degree)= \sin \: 90 \degree = 1 \\ \\ \cos 3A =\cos (3 \times 30 \degree)= \cos \: 90 \degree = 0\\\\ \tan 3A =\tan (3 \times 30 \degree)= \tan \: 90 \degree = \infty$

Which expression is equivalent to a2x2-2cx2 +a2y-2cy? (Polynomial Functions - Factoring)

lidiya [134]

<u>Given</u>:

The given expression is $a^2x^2-2cx^2+a^2y-2cy$

We need to determine the expression that is equivalent to the given expression.

<u>Equivalent expression:</u>

The equivalent expression can be determined by solving the expression.

Let us solve the polynomial function by factoring.

First, we shall group the expression.

Thus, we get;

$x^2(a^2-2c)+y(a^2-2c)$

Factoring out the common term $(a^2-2c)$ , we get;

$(x^2+y)(a^2-2c)$

Thus, the expression that is equivalent to the expression $a^2x^2-2cx^2+a^2y-2cy$ is $(x^2+y)(a^2-2c)$

Hence, the equivalent expression is $(x^2+y)(a^2-2c)$

Therefore, Option C is the correct answer.
