D^2y/dx^2+4dy/dx-12y=cos2x

rjkz [21]

If you're solving for x, you'd move all the terms containing x to the left side of the equation:

d^2y/dx^2+4y/x-12y-cos^2(x)+sin^2(x)=0

If you're solving for y, you'd simplify both sides of the equation, then isolating the variable:

y=xcos(2x)

Calculate the value of the following factorial expressions.

never [62]

Answer:

(a) 7

(b) 5040

(c) 336

(d) 132

Step-by-step explanation:

We have to calculate the value of given expression

(a) $\frac{7!}{6!}$

$\frac{7!}{6!}=\frac{7\times 6!}{6!}=7$

(b) $\frac{10!}{6!}=\frac{10\times 9\times 8\times 7\times 6!}{6!}=10\times 9\times 8\times 7=5040$

(c) $\frac{8!}{5!}=\frac{ 8\times 7\times 6\times 5!}{5!}= 8\times 7\times 6=336$

(d) $\frac{12!}{10!}=\frac{ 12\times 11\times 10!}{10!!}= 12\times 11=132$
