And notice that 13 12 is the reciprocal of 12 13 Now, secant of A is the reciprocal So instead of being adjacent over hypotenuse, which we got from the cah part of soh cah toa, it's hypotenuse over adjacent
- the concept of Tangent line – Khan Academy Help Center
Just as I explained the co-secant, the secant and co-secant have periods of length 2pi, and we don't consider amplitude for these curves The cotangent is the reciprocal of the tangent Wherever the tangent is zero, the cotangent will have a vertical asymptote; wherever the tangent has a vertical asymptote, the cotangent will have a zero

Now, secant of A is the reciprocal So instead of being adjacent over hypotenuse, which we got from the cah part of soh cah toa, it's hypotenuse over adjacent So what is the secant of A?
- Derivatives of sec (x) and csc (x) (video) | Khan Academy
We discover that the derivative of sec(x) can be written as sin(x) cos²(x) or tan(x)sec(x), and the derivative of csc(x) can be expressed as -cos(x) sin²(x) or -cot(x)csc(x) Let's explore the derivatives of sec(x) and csc(x) by expressing them as 1 cos(x) and 1 sin(x), respectively, and applying the quotient rule

- Using the Pythagorean trig identity - Khan Academy
Well that's the same thing as 1 2 times the reciprocal of this So times negative 2 over the square root of 3 These twos will cancel out and we are left with negative 1 over the square root of 3

Sir, if each identity is equal to one, then can we say that sin^2= = cos^2 = cot^2 - cosec^2 = sec^2 - tan^2?
