I don't want it done using a formula. I want to learn how to do it using cos, tan, sin or sin(a)/A = sin(b)/B, sin(b)/B=sin(c)/C.

Find θ and please explain!!! sin(43)=cos(θ)

Please show all work

Please show all work

Also find the: Amplitude: Period: Phase shift:

find values for sin θ, cos θ, cot θ, csc θ, sec θ (Include a diagram of a right triangle with hypotenuse in standard position)

A table might help

suppose cos theta = 5/9 and 3pi/2<theta<2pi. Sketch theta and theta/2 in standard position and label the intersection of these terminal sides with the unit circle.

Find the limit as x goes to 0: (ln(1+x2)-x(arctan(x)))/(x(sin(x)-x)) At first the fraction found is 0/0, but applying L'Hopitals rule, when differentiated...
