ENSP 338 Homework 1

This is a warmup to get you used to using the notebook for calculations.

In this homework, you will get acquainted with the Jupyter Notebook, which we will be using extensively in this class. You will need to sign up on SageMathCloud and pay the fee for this semester to use the tool. If you find yourself stuck, please read the computing tutorial.

from numpy import sin, cos, pi
#this import allows you to use trigonomic functions for this notebook
#example:
sin(0.1) # note that computers expect radians, not degrees
0.099833416646828155

Question 1

If ϕ\phi equals 30 degrees and aa equals 10, what is the value of asin⁡ϕcos⁡ϕ a\sin\phi\cos\phi

Hint: this should not be negative.

A1 = 4.33 #put your answer here

Question 2

If f=60f = 60, t=1t= 1 and ϕ=0.785\phi = 0.785 radians, what is the value of sin(2πft+ϕ) sin(2\pi f t + \phi) 

A2 = 0.375 # put your answer here

Question 3

If r1=10r_1 = 10 and r2=20r_2 = 20 what is the value of (1r1+1r2)−1 \left(\frac{1}{r_1} + \frac{1}{r_2}\right)^{-1} 

A3 = 6.67 # put your answer here

Question 4

If r=0.02r = 0.02 and n=10n = 10, what is the value of 1(1+r)n \frac{1}{(1 + r)^n} 

A4 = 0.82 # assign your answer to the variable A1
A4 # write out the contents of the variable A1
