If you need assistance, check the examples here. Some of the definitions and functions given in today's lecture are also helpful.
 
 
 

 1. Write MatLab commands for solving the following equations:
 

• 5x⁵+3x³+x=0
 
• x⁹+x=9
 
• 3x+5y+7z=9

  x -8y+2z=20
7x+2y -9z=-2
 
• 12x -8z=5

x+2y+z=11
9y+19z=39
 
 
2. Use MatLab language to write the following expressions:
 
• x=(1-e^-pi)/(1+e^-pi)
 
 
• y = |x| * sin(x+pi/5)
                          ______
• z=e^-(x+iy) * / x²+y⁴
 
 
• w= log₁₀(x+y+z)
