Find approximate solution(s) for the equation in the interval -pi < x < pi. cot x = 2sec x

a.

0.427

c.

0.427, 2.715

b.

1.571

d.

-1.571, 1.571

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
