How does Goblins work?

Three simple steps: (1) Share an assignment from thousands of standards-aligned topics using a share code. (2) Students speak and draw their thinking naturally, and Goblins responds with Socratic questioning that sounds just like their teacher. (3) Teachers get real-time formative insights showing what students struggle with and suggestions to inform instruction.

Does Goblins prevent cheating?

What grade level is NC.M3.F-TF taught?

This standard is part of the NC curriculum in North Carolina Standard Course of Study - Mathematics.

NC.M3.F-TF: Functions: Trigonometric Functions

Functions: Trigonometric Functions

NC.M3.F-TF.1Understand radian measure of an angle as:NC.M3.F-TF.1aThe ratio of the length of an arc on a circle subtended by the angle to its radius.NC.M3.F-TF.1bA dimensionless measure of length defined by the quotient of arc length and radius that is a real number.NC.M3.F-TF.1cThe domain for trigonometric functions.NC.M3.F-TF.2Build an understanding of trigonometric functions by using tables, graphs and technology to represent the cosine and sine functions.NC.M3.F-TF.2aInterpret the sine function as the relationship between the radian measure of an angle formed by the horizontal axis and a terminal ray on the unit circle and its y coordinate.NC.M3.F-TF.2bInterpret the cosine function as the relationship between the radian measure of an angle formed by the horizontal axis and a terminal ray on the unit circle and its x coordinate.NC.M3.F-TF.5Use technology to investigate the parameters, a, b, and h of a sine function, (x) = a * sin(b * x) + h, to represent periodic phenomena and interpret key features in terms of a context.
