Differentiate f() = ( − cos()) sin()

Mathematics
1 answer:
victus00 [196]3 years ago
7 0

Answer:

1

Step-by-step explanation:

f'(x) = -d(cos(x))/dx*sin(x) + d(sin(x))/dx * cos(x)

f'(x) = sin(x) * sin(x) + cos(x)*cos(x)

f'(x) = 1

I haven't got theta to comply with your request. The best I can do us use the word theta. x has exactly the same meaning, and the answer would be 1.

artcher [175]
Your answer would be x = 12.41 

6.15 (x - 8.86) = 21.83
      *6.15 * 6.15

6.15x - 54.49 = 21.83
         + 54.49  + 54.49

6.15x = 76.32
/6.15    /6.15

x = 12.41

Could you help me on this please !
Sergeu [11.5K]

Answer:

1 is allowed on the elevator.

2 is allowed on the elevator.

3 is allowed on the elevator.

4 is not allowed on the elevator.

5 is allowed on the elevator.

Step-by-step explanation:

If the maximum weight capacity of the elevator is 750 pounds, then that means every weight that is 750 pounds or less is allowed on the elevator.

1 is allowed because 700lbs is lower than 750lbs, therefore it is safe.

2 is allowed for the same reason, 620lbs is lower than 750lbs.

etc, etc.

So that's all you need to look for :)
