From the studies "This is a reprint of the unique variation of Lang’s ‘A First direction in Calculus’, which was once first released in 1964....The therapy is ‘as rigorous as any mathematician would want it’....[The workouts] are refreshingly easily acknowledged, with none extraneous verbiage, and every now and then particularly challenging....There are solutions to the entire routines set and a few supplementary difficulties on each one subject to tax even the main able." --Mathematical Gazette
