yes it is for homework, we are currently learning how to use math equations on the program

I actually don't know how to enter the problem on SageMath

2019-09-02 13:23:17 -0600 commented answer error for (3*e+2*I)*(-3+pi*I)

so is -30.7477217633110 + 19.6192026680207I , the correct answer? Because I don't think there is another way to type (3e+2I)(-3+pi*I)

2019-09-02 12:23:29 -0600 commented answer error for (3*e+2*I)*(-3+pi*I)

just SageMath?

if sin and cos are next to an absolute value, should I do sin*abs(x) or sin(abs(x) ?

2019-09-02 12:15:39 -0600 commented answer error for (3*e+2*I)*(-3+pi*I)

I entered (3e+2I)(-3+piI) and somehow got that answer

2019-09-02 12:07:52 -0600 asked a question error for (3*e+2*I)*(-3+pi*I)

so, I have to type in the problem (3e+2i)(−3+πi)...I enter in (3*e+2*I)*(-3+pi*I) on SageMath but come up with the answer, -30.74772176 + 19.61920267*I....am I dumb or is the correct answer?

2019-09-02 12:03:04 -0600 commented question how do I enter 2sin|1−3√2|cos|1+ 2√3|

oh I see, it seems I did not enter the correct amount of parentheses for the problem. thank you for the help :)

2019-09-02 10:44:08 -0600 asked a question how do I enter 2sin|1−3√2|cos|1+ 2√3|

when I enter it in SageMath as 2 * sin * abs(1-3 * sqrt(2))*cos*abs(1+2 * sqrt(3)) it does not run the code? your help would be very appreciated :)

2019-09-02 02:55:57 -0600 asked a question how do I enter (3e+2i)(−3+πi)?

every time I enter I to represent i, it comes as an invalid syntax? pls help :)
