Most math and science study guides are a reflection of the college professors who write them: dry, difficult, and pretentious. The Humongous Book of Trigonometry Problems is the exception. Author Mike Kelley has taken what appears to be a typical trigonometry workbook, chock full of solved problems—more than 750!—and made notes in the margins adding missing steps and simplifying concepts and solutions, so what would be baffling to students is made perfectly clear. No longer will befuddled students wonder where a particular answer came from or have to rely on trial and error to solve problems. And by learning how to interpret and solve problems as they are presented in a standard trigonometry course, students become fully prepared to solve those difficult, obscure problems that were never discussed in class but always seem to find their way onto exams.

He loves his new ball
Color: Paw Print, Size: 8 inches
My German Shepherd loves it. The only issue we had is that he managed to tear the black handle off within 5 minutes, so we just ended up cutting it completely off. Other than that he loves it.

Great Dog Toy!
Color: Paw Print, Size: 8 inches
This soccer ball gets even my LAZY dog moving! It's so fun for them to play with and tug with. Great product, will need to keep re-buying it whenever it gets a hole in it from the rough wear and tear of my pups! :)

Very durable ball

It’s hardy 2 dogs can play with it at the same time. The last one lasted almost 2 years with every day play and chewing.

Durable and great value
Color: Paw Print, Size: 8 inches
Best thing we ever bought our Frenchie. It keeps him busy and he gets a great workout in. The tabs make it easier and for me to grab and throw for him. They also allow him to grab them and run with the ball. Only thing he hasn't destroys. Very durable and easy to inflate with enclosed pump.
