Question

which one is the easy way to remember trigonometric ratios? soh ceh toa sah coh toa soh cah tao soh cah toa

Explanation:

Step1: Recall trigonometric ratios

$\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$, $\tan\theta=\frac{\text{opposite}}{\text{adjacent}}$

Step2: Analyze mnemonic

Soh Cah Toa:

• Soh: $\sin$ (S) = Opposite (O)/Hypotenuse (H)
• Cah: $\cos$ (C) = Adjacent (A)/Hypotenuse (H)
• Toa: $\tan$ (T) = Opposite (O)/Adjacent (A)

Answer:

Soh Cah Toa
