Minimum value for the desk download the diagram from the attachment. some are actually confused so you must download the picture. Two corridors meet at right angles and are 2m and 3m wide respectively. Θ is the angle marked on the given figure and ABCD is a desk which must be kept...

1) a and b are variables related by the equation ab^3 = 40. At the instant when a = 5, b is increasing at 1 unit per second. What is happening to a at this instant? 2) A right angled triangle ABC has a fixed hypotenuse AC of length 10cm, and side AB increases at 0.1cm per second. At what...

given that Θ = arctan 3/x - arctan 2/x prove dΘ/dx = (2 / x^2+4) - ( 3 / x^2+9) hence find x when dΘ/ dx = 0 incase you need an answer ANS. x = root 6 All i need is prof of that thing... soo hardd -_- DO NOT GIVE ME ANY LINKS..I NEED workingss. thanks australian international...
