I have been tutoring mathematics for 6 years during my high school and university. Currently, I am studying Math master program in University of Vienna, and working in Geometric Analysis (Contact me if you want to see my publication) I can provide either online or face-to-face private lesson in Vienna about Calculus, Linear algebra, Multivariable Calculus and Real/Complex/Functional analysis, PDE and Differential Geometry. In Hong Kong, I also have tutoring Mathematics and Calculus for secondary school student.My student got a good grade in university and for high school. One of my student got admitted to UCL math bachelor program. I will provide exercise and demonstration to teach the problem solving technique. I also use desmo and other tools for helping student visualize the Geometry behind in an abstract mathematics concept. The student can ask for homework help after the tutorial. I am happy to provide detail explanation and solution. Do not hesitate to contact me for more information, guaranteed response in a few minutes up to 10 hours maximum.
