Solve this logarithmic equation. 3 log 2 base x + log 18 base x = 2

maths
Solve this equation. 3^2x - 3^x+2 = 3^x - 9

maths
Proof this identities. (a) sin x cot x = cos x

maths
Please I need help.Show full working out. (a) sin x cot x= cos x (b) (1 + tan theta)^2 + (1- tan theta)^2 = 2sec^2theta

maths
Please help me simplify this and show full working out. (a) (2x^3 divide 3y^4)^2 multiply (x divide 3y)^-2 (b) a-a^-1 divide a^2 - 1 (c) 3^a+2 times 9^2a+1 divide by 6^2 times 3^5a+3

Maths
Ship A is 18.5km from a port P on a beearing of 045 degree and ship B is 26.4km from point P on a bearing of 105 degree. Calculate the bearing of A from B and the distance AB.

Maths
Please help me.Iam stuck. Find all the possible values of theta between 0 degree and 360 degree for the following quadratic equation. State the quadrants in which each angle lie. 8 tan^2 theta + 2 tan theta=15
