Answer: The first option.
Step-by-step explanation:
1. You need to remember that:
- An even function is a function with the following property:
f(-x)=f(x)
- An odd function is a function with the following property:
f(-x)=-f(x)
2. By definition, the contangent is an odd function, therefore you have that:
cot(-θ)=-cot(θ)
Then:
3. So, you can coclude that the first step is wrong. Therefore, the answer is the first option.
x=0.295 this is the correct answer
Answer:
x=5/2
y=2
z=-1/2
Step-by-step explanation:
We are given that
We have to solve the system of equation by using inverse matrix method.
We know that
AX=B
Where
A
=
Now,Minor
,,
,,
,,
Co-factor
Now, adjoint
Now,
Now,
We get
x=5/2
y=2
z=-1/2
