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

Lorico [155]

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)

Use the distributive property to show why the product (-6)(-3) is positive .

Alla [95]

Porque menos por menos es más es una regla

Si multiplicas (-6)(-3) La respuesta es 18 es positivo porque se cumple la regla de menos por menos es más

REPASA

MENOS POR MENOS = MÁS

MÁS POR MÁS = MÁS

MAS POR MENOS = MENOS

MENOS POR MAS = MENOS
