# Precalculus

Precalculus is a precise itinerary designed to challenge and develop your understanding of mathematics.  This course will prepare you for College Calculus or Calculus AP.  Precalculus is an elective course, and ask-math  commend all who want to continue their study of mathematics.  Students with a strong math background and those who expect to spend substantial time learning, ready for the hard work and  practicing the concepts presented should be enrolled in this particular course.

Intercept of rational function : An intercept of rational function is a point where the graph of the given function intersect or cut the X and Y axis.
how to find horizontal asymptotes : In the rational functions if the degree of numerator and denominators are same then the horizontal asymptote is y = (numerator's leading coefficient) / (denominator's leading coefficient)
how to find vertical asymptotes : Vertical asymptote can be found by making the denominator equal to zero.
how to find slant asymptotes : If the degree of numerator is greater than the degree of denominator by the margin of 1 then we have a slant asymptote.
graph a rational function : For graphing a rational function, the properties such as domain, vertical and horizontal asymptotes of a rational function are also investigated.
inverse sine function : The inverse sine function $sin^{-1}$ gives the ratio opposite/hypotenuse and gives the angle θ
inverse cos function: The inverse cosine function $cos-1$ gives the ratio adjacent/hypotenuse and gives the angle θ
inverse tan function : The inverse tangent function $tan-1$ gives the ratio opposite/adjacent and gives the angle θ
inverse trigonometric function arccosecx : The inverse arccosecant function cosec-1 gives the ratio hypotenuse/ opposite and gives the angle θ
inverse secant function : The inverse secant function $sec-1$(hypotense/adjacent) and gives the angle θ
law of sines : The law of sines can be used to find the remaining sides of a triangle when two angles and a side are given.
law of cosines: The law of cosines is useful for computing the third side of a triangle when two sides and angle between them is given and in finding the angles of a triangle if all three sides are given.
Circular function : Unit circle is used in the circular function.
parabola function : Parabolic function frequently used in physics, engineering, and many other areas.
Ellipse : Ellipse is a curve in a plane with two focal points.
