Your Ti-Nspire programs are my drug of choice, they are addictive, will enjoy them for rest of my life

Thank you.  I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; 

but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available.   

These apps you sell have the potential to become addictive so I most likely will be back for more!  

I think I made the right choice.

So, needless to say, I am very impressed.

Beauty is in the eye of the beholder.  Your programs are my drug of choice.  

I am sure to enjoy them for the remainder of my life.  

They are one of the few things worth buying besides food and a good pair of boots.

Impressed with Calculus Made Easy for Ti-Nspire

Hi Mike

I was so impressed with CME that I bought AME and PME and they are both first-rate.

I’ll be buying more as they appear.

Your apps have made the Nspire a lot more useful to me than it was – in fact, I’m beginning to like it quite a lot.

Congratulations on the hard work, I suspect your nspire apps will be even more successful than the Ti89 apps.

Best wishes

How to Enter and Solve Logarithms with different bases using the Ti-Nspire CX

Entering Logarithms using different bases (which are the subscripts after log) is very easy. Say we want to enter log(3x) using base 10 : by default the Ti-Nspire Cx uses base 10 as the default and we just type in log(3x) as shown below:

Pressing ENTER then shows:

The image above shows how to change to base 2 logarithm. Pressing ENTER then shows the subscript 2 indicating base 2 Logarithm.

Lastly we are changing our expression to 3x+1 and use Logarithm base 7. Pressing Enter shows our desired expression

Lastly, you can solve Logarithmic Equations such log4(3x+1)=1 in two different ways:

Either you can type in solve(log4(3x+1)=1,x) and press ENTER.

Or, you define your Equation first using eq:=log4(3x+1)=1 and then type solve(eq,x).

Pick the method you prefer, they both work equally.

BTW, the solution is x=1 since log4(41)=1 and 3x+1 = 4 when x=1 . Always remember that the Logarithm is the Exponent of a Power as long as the two bases (subscript and the Base of the Power, here both are 4) match.
