Question

Use Python to solve each problem. Answers should be written in full sentences.

1. Define a code that will give users the option to do one of the following.

   • Convert an angle from radians to degrees,

   • Convert an angle from degrees to radians,

   • Return the sine, cosine, or tangent of a given angle (need to know if angle is given in degrees or radians).

Answer 1

PYTHON PROGRAM:

import math 

#options to choose operation from...
print("\nchoose any one of the following operations:")
print("1 convert an angle from degree to radian\n2 convert an angle from radian to degree")
print("3 find sine of angle\n4find cosine of angle\n5 find tangent of angle")
#input option 
n=int(input())

print()
#taking input of angle
x=float(input("Enter angle: "))
print()

#conditions and calculations for corresponding options

if n==1:
    print("In radian: ",round(x*math.pi/180,6))  #degree to radian upto 6 decimal place
    
elif n==2:
    print("In degree: ",round(x*180/math.pi,6))  #radian to degree upto 6 decimal place

#options to find sine, cosine or tangent
elif n==3 or n==4 or n==5:
    #input for type of angle i.e. degree or radian
    t=int(input("Choose type of input:\n1 degree\n2radian\n"))
    print()
    #if degree type
    if t==1:
        if n==3:
            print("sine of angle: ",round(math.sin(x*math.pi/180),6))  #sine of degree upto 6 decimal places
        elif n==4:
            print("cosine of angle: ",round(math.cos(x*math.pi/180),6))  #cosine of degree upto 6 decimal places
        elif n==5:
            print("tangent of angle: ",round(math.tan(x*math.pi/180),6))  #tangent of degree upto 6 decimal places
            
    #if radian type
    if t==2:
        
        if n==3:
            print("sine of angle: ",round(math.sin(x),6))  #sine of radian upto 6 decimal places
            
        elif n==4:
            print("cosine of angle: ",round(math.cos(x),6))   #cosine of radian upto 6 decimal places
            
        elif n==5:
            print("tangent of angle: ",round(math.tan(x),6))   #tangent of radian upto 6 decimal places
