While there is no doubt that the student can solve a variety of problems, the contents are not explained at all. The concepts are as abstract as ever and ii is authors like this who have made Maths look so complex over the years. Emphasis on why certain steps are carried out os given way more to English.
Good book for students who have very good basics but a very very bad book for beginners and who want to be self taught.
Users may like to note the following
Page 483 has errors that have been there since the first edition.
r^(1/3) should be (-1q/3)^(1/2) and tan(theta) = b/a should be cos(theta) = -r/2/(-a^3/27)^(1/2)
I have informed Elibron ( using symbols for theta and square root and superscript for power)
