# Question 1: Write a lambda expression which takes an argument x as a parameter and simply returns x.

# Assign this expression to a variable named my_lambda_func.

## Write your code below, 1 line

my_lambda_func = lambda x:x

print(my_lambda_func(7))

## End question 1

# Question 2: Print the type of my_lambda_func. Hint: did you accidentally call the function?

## Write your code below, 1 line

print(type(my_lambda_func))

## End question 2

# Question 3: Write a lambda expression which returns the cosine of an argument x and assign it

# to a variable named my_cos. Hint: math module

## Write your code below, 2 lines

import math

my_cos = lambda x: math.cos(x)

print(my_cos(45))

## End question 3

# Question 4: Write a lambda expression which models this equation f(x) = x^3 + 3x^2 + 200.

# Asssign it to a variable my_eq1

## Write your code below, 1 line

f = lambda x : x^3 + 3*x^2 + 200

print(f(10))

print(1000^3)

## End question 4

# Question 5: Write a lambda expression which models this equation f(x,y,z) = x^3 + 3y^2 + z

# where z is optional. If no value for z is provided use the default value of 100.

# Assign this expression to a variable my_eq2

## Write your code below, 1 line

f = lambda x,y,z=100 : x^3 + 3*x^2 + 200

print(f(100,34))

## End question 5
