(1-cos0)(1+cos0) pls help​

Mathematics
1 answer:
topjm [15]4 years ago
6 0

Answer:

sin²Ф

Step-by-step explanation:

I doubt that you actually meant "cos 0" ... that has a value of 1.

If you meant  (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.

That, in turn, is equal to sin²Ф

If 2x+4 = (x²)²÷2 then what is x?
Leviafan [203]

Answer:

Below.

Step-by-step explanation:

2x+4 = (x²)²÷2

2x + 4 = x^4/2

x^4 = 4x + 8

x^4 - 4x - 8 = 0

We can try trial an error to solve this

Looks like x = 2 fits it:

2^4 - 4(2) - 8

= 16 -8 -8 = 0

so x = 2 is one solution.

I can't find any other solution among other integers.

To find the other solutions you can draw a graph manually or by using software.

There will be either 1 or 3 more real solutions.

I used software to draw the graph and found one other solution:

x = -1.296
