What is the domain of y=cot x?

Mathematics
1 answer:
MissTica3 years ago
5 0

We have to find the domain of y = cotx

We know that cotx = cos x / sinx

And also when sinx becomes zero cotx becomes undefined

And again we know that value of cosx and sinx can be between -1 to 1

But value of cotx can lie in between -∞ to +∞

Just for example cot30 is cos30 / sin30

= √3/2/1/2 = √3

Therefore domain of cotx is x

x ∈ R , x ≠ πn for any integer n

Then you multiply 4.75 times 2       (9.5)

Then you add the 2 numbers to get the answer.

0.95 + 9.5 = 10.45

With the calculator, just put in the 2 numbers and click enter!

Find the shaded area ..
never [62]

Answer:

39°

Step-by-step explanation:

The angle adjacent to 115° in the lower triangle = 180° - 115° = 65°

angle on circle in lower triangle

= 180° - (65 + 76)°  ← angle sum in triangle

= 180° - 141° = 39°

Angles on the circle subtended from the same arc are congruent, then

shaded angle = 39°
