... We can remember the signs of the trig values in the following ways. Cosine and sine are very closely related to values of x and y. Anywhere x is positive, cosine is positive. Wherever y is negative, sine will be negative. Tangent is similar to slope. Picturing a positive sloping line tells us that ...
