Trigonometric vs CloudLabs Metal foundry

Learn trigonometry by seeing it move. Trigonometric turns every formula into something you can drag, spin and explore — free, with no ads, no accounts and no internet needed. UNIT CIRCLE • Drag point A round the circle or use the slider and play button • Change the radius OA and read x = OA·cos θ, y = OA·sin θ, arc length AB, circumference and sector area • Exact values such as √3/2, angles in degrees and as multiples of π, quadrant signs (All–Sin–Tan–Cos) and the tangent line 3D SPHERE — SPHERICAL COORDINATES • Place a point P(r, θ, φ) on a glass sphere you turn with your finger • See it converted to x, y, z and back, with top and side views • Explore the volume element r² sin θ dr dθ dφ GRAPHS • A rotating circle draws sin, cos and tan, projected straight onto the curve • Reshape y = A·f(Bx + C) + D with sliders and read amplitude, period, phase shift and midline • Type your own formula — or try examples like a Fourier square wave, a damped wave or beats TRIANGLE SOLVER • Solve any triangle from three values: SSS, SAS, ASA/AAS and the ambiguous SSA case • Drawn to scale, with area, perimeter and every step of the working FORMULAS & QUIZ • A searchable cheat sheet of identities, the laws of sines and cosines and the special-angle table • Quick ten-question quizzes with an explanation after every answer Three colour themes, full iPad support and a side-by-side landscape layout. Made for students, teachers and anyone curious about trigonometry.

In this lab practice, you will use the properties of logarithms to determine the melting point and the emptying time in which three different materials reach the melting point. The simulator provides a thermometer, a melting furnace and a mold.
