Derivatives of sin x, cos x, tan x, e^x and ln x | Derivatives of common functions | Khan Academy64歲的建築師Octavio Mendoza 在他有生之年,用“烘烤”的方法完成了一幢房子。他把這幢5400英尺的房子稱作“世界上最大的陶瓷”。Casa Terracotta 或稱作西班牙語Casa Barro,是一幢以粘土為原料手工製作的陶瓷屋,並且Lets say I have an equation sin x = 1/2. Then clearly, x = 30 degrees or pi/6 radians. Now if I differentiate both sides of the equation with respect to x (because both are equal, their derivatives should also be equal), I will have cos x = 0, right? But ...
