∫ cos(x)/sin2(x) dx = -cosec(x) + C C is the constant of integration.
It is 1.
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
Yes, the sine, cosine and tangent are integral to problem solving (angles and side lengths) in right angle triangles (triangles with a 90 degree angle included).
No, it does not.
∫ 1/sinh2(x) dx = -cotanh + C C is the constant of integration.
∫ sinh(x) dx = cosh(x) + C C is the constant of integration.
∫ 1/sin2(x) dx = -cot(x) + CC is the constant of integration.
∫ 1/sin(x) dx = ln(tan(x/2)) + C C is the constant of integration.
The basic ones are: sine, cosine, tangent, cosecant, secant, cotangent; Less common ones are: arcsine, arccosine, arctangent, arccosecant, arcsecant, arccotangent; hyperbolic sine, hyperbolic cosine, hyperbolic tangent, hyperbolic cosecant, hyperbolic secant, hyperbolic cotangent; hyperbolic arcsine, hyperbolic arccosine, hyperbolic arctangent, hyperbolic arccosecant, hyperbolic arcsecant, hyperbolic arccotangent.
