Only if you don't study...
it is hard if you don't get it or if you didn't study. it will be easy if you study it and you get everything.
Why? These are two topics within Mathematics. They are not isolated, mutually-insular academic disciplines. Having said that, basic Trigonometry is simpler than Calculus, which requires the deeper grounding in algebra and the graphs of algebraic functions based on x^n where the index n is at least 2 (quadratic and higher-order equations) . At a more advanced level, all three topics merge when you apply calculus to trigonometrical functions.Many times, calculus classes will expect some basic knowledge of trigonometry. While it may not be too hard to learn in the class, you may feel better prepared if you have taken trigonometry or a pre-calculus class.
Some do, some don't: as with any subject. Also, in many cultures it is unfortunately acceptable to say that you find maths hard. You would not find as many saying that about other subjects.
The people make it hard to make you think so you can learn stuff..
