What is the sign of the product (ā4)(6)(9)(3)?
Positive, because the products (ā4)(6) and (9)(3) are negative and the product of two negative numbers is positive
Positive, because the products (ā4)(6) and (9)(3) are positive and the product of two positive numbers is positive
Negative, because the product (ā4)(6) is negative and the product (9)(3) is positive, and the product of a negative number and a positive number is negative
Negative, because the product (ā4)(6) is negative and the product (9)(3) is negative, and the product of two negative numbers is a negative number

Prove (a) cosh2(x) ā sinh2(x) = 1 and (b) 1 ā tanh 2(x) = sech 2(x). solution (a) cosh2(x) ā sinh2(x) = ex + eāx 2 2 ā 2 = e2x + 2 + eā2x 4 ā = 4 = . (b) we start with the identity proved in part (a): cosh2(x) ā sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 ā sinh2(x) cosh2(x) = 1 or 1 ā tanh 2(x) = .
