Traceback (most recent call last):

File “C:\Users\xxxxxx\YYYY\zzzz\xxxx\Testing 543.py”, line 17, in

a_squared = b*b+c*c-2*b*c*math.cos(A)

TypeError: unsupported operand type(s) for *: ‘function’ and ‘function’

In addition to the one error i had when I done this before:

", line 17, in

a_squared = b**2+c**2-2*b*c*math.cos(A)

TypeError: unsupported operand type(s) for ** or pow(): ‘function’ and ‘int’

<What do you expect to happen instead?>

I am a beginner and I am interested in programming. I am attempting to create a program to work out side a in the mathematics trig cosine rule. I will be using this to help me in my exams. I expect the output to give me a integer but im ending up with the same errors.

I am very new to this program and I just found this website so please help me people. I enjoy doing programming… Anyways, I realised the problem is with the formula as the variables b,c,A are being recognised as variables despite puting int or float. I need help

#This is a simple sample program

import math

def b():

int(input(“What value is side b”)

)

def c():

int(input(“What value is side c”)

)

def A():

int(input(“What value is angle A”)

)

a_squared = b*b+c*c-2*b*c*math.cos(A)

print(“The answer to side a squared is” ,a_squared)
