## Why is there this inconsistency with the...

I am plotting a simple rational function. When the denominator is completely factored, the discont command works as expected. However, if the denominator is expanded, discont fails.

Why does this happen?

This behavior also occurs in Maple 17.

Maple

Why does:

Student[Calculus1]:-Tangent(tan(3*x)-5*exp(-x^3),x=0,output=plot,gridlines=true,caption="")

produce the following error?

Error, (in plots:-display) integer or integer range expected in op list

## Animate Polar Area Being Filled as Curve...

Maple 17

I am using the following commands to create an animation of a simple cardioid being traced out. I would like to add to this an animation of the filling of the region bounded by the curve and the coordinate axes as the curve is being traced out. How might one achieve this?

with(plots):

animatecurve([2-2*sin(theta),theta,theta=0.. 2*Pi],coords=polar,axiscoordinates=polar,frames=250, numpoints=300, scaling=constrained)

Thanks.

Maple 17

I would like to express 2*sin(x+Pi/4) in the form sqrt(2)*sin(x)+sqrt(2)*cos(x). I've tried many variations using simplify/expand/combine/etc. to no avail. Any ideas?

## Why are there extra characters when usin...

Maple 17

I am playing around with a crude implementation of the bisection algorithm. I am using printf  to display some of the output, however there are a couple extra characters, namely, ()^2, at the end. When the very last line is removed, it goes away. What is causing this?
