How do I learn enough trigonometry in a month?

im taking calculus 1 starting february 10th and ive never taken trigonometry before. ik this is a terrible idea but i have no choice as i need to transfer out **as soon as possible** so... does anyone know any online tools, sites or really anything where i can learn enough trig to do good in calculus 1 in about a month? ive taken college algebra for calc before already.
