<p>what's up guys?
How do you guys solve these problems?
I know these are easy for you guys but not for me!
Please give me a hand.</p>
<ol>
<li><p>Find dy/dx
y=x^3sin^4x</p></li>
<li><p>Find all values of the constants m and b for which the fuction is continuous at x=pi. And Differentiable at x=pi.</p>
<p>sinx, x<pi
mx+b, x is greater than/equal to pi
(y= is in front of two equations)
Many thanx in advance.</p></li>
