WebGIF (1) = 1 and by the same definition, GIF (1.1) = 1, GIF (1.2) = 1, etc. So by the definition of continuity at a point, the left and right hand limits of the GIF function at integers will always be different - therefore, no limit will exist at the integers, even though integers are in the domain of the function. Hope this helps :) WebCos θ = Base/Hypotenuse. Tan θ = Perpendicular/Base. Perpendicular is the side opposite to the angle θ. The base is the adjacent side to the angle θ. The hypotenuse is the side opposite to the right angle. The other three functions i.e. cot, sec and cosec depend on tan, cos and sin respectively, such as: Cot θ = 1/tan θ. Sec θ = 1/cos θ
