Question

Enkhzaya Enkhtaivan · Answer

we have Y double prime plus y is equal to 4x, cosine x here. Now, again, the initial guess would

Ankit Singh · Answer

So in this problem basically we need to rewrite the cost 4x entrance of x. So we have cost of 4x

Lauren Shelton · Answer

So where have I seen this relationship before? Coside of one angle times cosine of the other ang

Aman Gupta · Answer

In this problem, the given equation can be rewritten as cost 4x can written as cost square of 2x

Piyush Kumar Gupta · Answer

I&#x27;m a teacher for this question and our question says that right exactly cost 4x in terms of sin
