Are you ready to improve your grade in pre-Calculus (aka Trigonometry)? I'd love to help understand the math course you're taking and have fun with it.

If you need assistance with your Trigonometry class to understand the way it is presented in the book, I’ll help you comprehend every lesson. We can even try an alternate method until the light bulb comes on. Because once you understand a concept, you can return to the required method.

My only goal is for you to succeed!

Concepts in Trigonometry:
Complex Numbers
Trigonometry Functions – arc, sine, cosine, tangent
Logarithmic Functions
Graphing – Polar, Rectangular
Pythagorean Identity
Radians & Degrees
Exponential Functions
Word problems

I’m also a devotee of grammar and proofreading skills. I have been hired be several published authors to proofread their novels prior to publications. So if you need assistance with improving your Writing Skills, I am available for this as well – two tutors for the “price” of one.

About Mary Lou H.

I graduated from Indiana University of Pennsylvania with a Bachelor of Science in Education/Mathematics. I am a "real" math teacher.

I have taught math to elementary students, algebra and geometry in junior high and high school, and all levels for college students.

For example, my first student had dropped out of high school and had the opportunity to earn a diploma rather than a GED. She only needed her math credit. I was so proud to share my graduation gown from my closet with her and provide her with an authentic graduation picture when we finished.

I have also helped a grandmother earn her GED, a mother earn her MBA, several young men prepare for the ASVABs (military entry test) and many students navigate through math, pre-algebra, algebra, and geometry courses on their way to high school graduation. I would love for you to be my next success story!

I couldn't imagine a better teacher. I was skeptical at first being the classes are online, however, I have immensely improved in my typing accuracy with only 10 short classes. It has been a wonderful experience and I will definitely be going to Mary Lou for any other lessons me or my son will need!
