...Trigonometry explores the graph of the functions of f(t) = A sin (Bt + C) and f(t) = A cos (Bt + C) and interpret A, B, and C in terms of amplitude, frequency, period, and phase shift, defines the tangent, cotangent, secant and cosecant functions and can graph them, discovers the tangent of the angle that a line makes with the x-axis is equal to... read more

...I have worked with students of all ages, from over 30 different countries, from absolute beginners learning their very first words to advanced students seeking an additional edge. I have a variety of effective and fun techniques that make learning English easier. I tailor my lessons to meet the needs of each individual student. I help students overcome... read more

...I'd be happy to work with you to help you understand these and more: - how to measure angles in radians and what it means for an angle to be in standard position in the coordinate plane. - definitions of the six trig functions - sine, cosine, tangent, cotangent, secant, co-secant - trig identities - graphing trig functions: period, amplitude, horizontal... read more

...I am patient and love the challenge of finding multiple ways of explaining a concept until complete understanding is accomplished. I have taught Algebra II at high schools and community colleges. I currently teach an online version of this course. I have a special method that I devised for factoring trinomials that my students love. I have taught... read more

...Its clean syntax is used in later languages such as C++, Java and Visual C#. Knowledge of C is still required by most college Computer Science programs. When I first began using C in 1977 I was amazed by its clarity and simplicity, compared to the older languages I used at the time, COBOL and FORTRAN. C was the true beginning for me of a life-long... read more
