Solve for x, 1.5x-(e^x)cosx=0, accurate to 2 d.ps. Hint: to expand (e^x)cosx or use other mean. Thanks in advance.?

1.5x-(e^x)cosx=0=>

y=1.5x=(e^x)cosx

what we to do is to find the intersection

of

y=1.5x ---------(1)

y=(e^x)cosx-------(2)

(2) is a periodic function & its amplitude

is increasing=> there are infinitely many

solutions of x.

The smallest +ve solution I found is

x=0.9863146...=>

x=0.98631 is an answer accurate to 5

d.ps.

I can't help you to much but if you go on the website Mathpapa. It should help you.
