Say you need to compute an integral such as :
using your trusty Ti-Nspire CX.
Typing those powers into your Ti-Nspire is different from what is shown in the image. You will have to type in sin(x)^2 and cos(x)^3 instead, where ^ is the exponentiation symbol.
Typing in sin^2(x) matches the given image/problem but the Ti-Nspire cannot digest this sequence of characters. It thinks that a variable called sin needs to be squared and multiplied by (x) at the end. That’s very different from the actual problem.
Here is what you need to type in to solve above problem:
integral(6*sin(x)^2*cos(x)^3,x)
Voila!
Expert tip : Any trig expression is expressed in terms of sin(x) and cos(x) using the Ti-Nspire CX . Ex: Typing in sec(x) will be shown as 1/cos(x) ,
Typing in sec(x)*tan(x) will be shown as sin(x)/cos(x)^2 which is different from your textbook answers.
