I'll just do some  examples

\(\sqrt2+\sqrt3\qquad \mbox{Cannot be simplified}\\ \sqrt2-\sqrt3\qquad \mbox{Cannot be simplified}\\ \sqrt2*\sqrt3=\sqrt{2*3}=\sqrt6\\ \sqrt2\div\sqrt3=\frac{\sqrt2}{\sqrt3}=\sqrt{\frac{2}{3}}\)

Although the first two cannot be simplified they are still added together.  :)

You can approximate a single number answer if you want to.

A milliamp is one 1000th of an amp.

(sin23)^2

It doesn't display the way I would like but it does give the correct answer.

(except for a little rounding error - that is normal)

\((\sqrt5*\sqrt{20})^2\\ =(\sqrt{100})^2\\ =100 \)

The square root and the square cancel each other out :)

Hi Jmsoh :))

Lets say your nominal annual interest rate is 8% and it is compounding monthly.

then

\((1+\frac{0.08}{12})^{12}=(1+r)^1\\ 1.0829995\approx1+r\\ r\approx 0.0829995\)

So the effective interest rate would be approximately  8.3%

For instance

cos 23⁰  =  0.9205

so

cos^-1 0.9205  =  23⁰

to get it on the web2.0 calc  press [2nd] then [acos]

There is also a toggle button at the bottom that sets the angle to degrees or radians :)

Hi Takahiro,

It is really good to see you :))

Have you fallen off any logs recently Chris ?

I think falling off a log on purpose might be quite difficult to do... of course it is much easier if you don't mean too :))

(1.03)t = 2 × (1.01)t

10.3t = 2.02t

Our answering guest is almost right.  :)

This can only be true if   t=0
