Decide first whether your function arguments represent radian or degree measure. Set your calculator mode appropriately.
(a) press the decimal point key, press the 9 key, press the sign change (+/-) key, press the "sin" key.
(b) press the 1 key, press the decimal point key, press the 8 key, press the "cos" key, press the reciprocal (1/x) key.
