Question

Using Microsoft Maple.

What are the maple commands and outputs for these 3 ?

1. "Use the solve for the following questions" $ax^2+bx+c=0$

2. "Use the expand command to multiply out the following" $sin(\alpha + \beta )$   

3. "Use the expand command to multiply out the following and then use factor" $sin(3a)$

Answer 1

We can write the maple commands like below.

1. a*x^2+b*x+c = 0

2. expand($sin(\alpha +\beta )$) --> $sin(\alpha)cos(\beta) + cos(\alpha)sin(\beta)$

3. factor(expand($sin(3a)$) --> factor($-4sin^3(a)+3sin(a)$) --> $-sin(a)(4sin^2(a)-3)$
