No, it is not. To be correct, the expression requires parenthesis, which are missing.
No, it does not.
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
The inverse of sine (sin) is cosecant (csc). The inverse of cosine (cos) is secant (sec). The inverse of tangent (tan) is cotangent (cot).
It is 1.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '

Assuming that "secany" is meant to be secant, the answer is cosecant.
