Another example:

0.4^5   = 0.4*0.4*0.4*0.4*0.4  =  0.01024

so

0.01024^(1/5) must equal  0.4

It is becasue if you raise a number less then 1 to a power greater than 1 then the answer is smaller as in this example.

In your example

0.8479510815230789^(100/18) = 0.4

so

0.4^(18/100)=0.8479510815230789

I interpreted the question a little differently from you asinus but the type of algegra is similar anyway  :)

There is no range because there is no y in the equation   

asinus has solved the equation for you.

Es gibt keinen Bereich, weil es kein y in der Gleichung gibt
Asinus hat die Gleichung für Sie gelöst.

Inverse cos is the same as arc cos

Use   acos   etc

Yes ...   What you going to do about it ??       

Thanks for the points :))

Don't you play with Desmos?  It is not that hard and it is fun making these diagrams.

I think Geogebra is harder, it is less intuitive especially when you are new at it.   :/

Thanks Chris,

Yes, took forever but I can use Desmos a little better now :))

It is fun drawing these pics and this one was a bit of a challenge.

I tried to come up with that distance without Wolfram|alpha but I couldn't get the numbers to fall out.  

I guess I was doing something wrong....... :(

Hi Chris,

Did you just know 

"2^2 + 3^2 + 5^2 + 7^2 + 11^2 + 13^2 + 17^2  =  666 =  sum of the squares of the 1st seven primes...!!!"

Or did you google it?       

I think you knew it your have always been fascinated with 666   

tan(x)=o.67

inverse tan (0.67) = atan(0.67)

atan(0.67) = 33.822085217494 degrees
