I need to use the distance formula below to find the exact corordinates of the terminal point of pi/8 from pi/4 and then solve for (b) and then (c ). It has to use the distance formula not half angle formula of cosine and sine. Please include your step by step solution. Thank you. The point at x/8 is halfway between 0 and x/4. So, if its coordinates are (x,y), then we have d[(x,y),(1,0)) = d[(x,y). (7312, V3/2)) which is...
