Question

Discuss the continuity of the cosine, cosecant, secant and cotangent functions.​

Answer 1

Step-by-step explanation:

The values of the functions matche with those of the limits as x goes to 0 (Remind the definition of continuity we have). ... - sin(x) goes to 0 means that the fraction as a whole goes to 0. - x goes to 0 means that the function as a whole goes to +∞.
