Question

what is 1 - cos =______​

Answer 1

Answer:

By formula ,

Cos(A) - cos(B) =2{sin(A+B)/2}.{sin (B-A)/2}

1-cos(x) = 2{sin(0+x)/2}.{sin(x-0)/2}

1- cos(x) = 2sin(x/2).Sin(x/2)

1-cos(x) = 2sin^2(x/2)

Ans. = 2sin^2(x/2)

Step-by-step explanation:

Answer 2

Answer:

here is your explanation

Step-by-step explanation:

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
