I am trying to do combinations on my calculator, but I can't find a button to do nCr problems.
This dot product calculator comes in handy when you have to solve vector multiplication problems that are not so easy to solve manually. Rather than calculate your problems and scalar product by hand you can calculate the same problem with our tool which is really great and it's doesn't take much time and also you don't have to solve it manually.

There is no such key on this calculator. You can calculate it using factorials. To calculate nCr you can calculate n! / (r! * (n-r)!).
SOURCE: i want to calculate permutation and combination.
Hello,
Use the sequence [2ndF][nPr] for permutations and [2ndF][nCr] for combinations.
Exemples: 10(nPr)3 is entered as 10[2ndF][nPr]3 [=] gives 720
5(nCr)2 is entered as 5 [2ndF][nCr] 2 [=] gives 10
Hope it helps.

Hi,
The source of errors is most certainly due to the wrong schoice of angle unit (degree or radian). If the default angle unit set in your calculator is the degree, any value fed to the trigonometric functions (sin, cos, tan) is considered to be expressed in degrees. Consequently, if you calculate the arctangent ( tan^-1) of a value, the angle returend by that inverse trigonometric function is expressed implicitly in degrees.
Similarly if radian is the default angle unit in your calculator, any angle returned by an inverse trigonometric function (arcos, arcsin, arctan) is in radian.
Set the default angle unit as the one required by your problem at hand. This way, the angles returned will be in the right unit and you will not have a problem of interpretation.
Hope it helps.
