Nah I use a hand trick: on my right hand my pinky = 0°, ring finger = 30°, middle = 45°, pointer = 60°, and thumb = 90°. If a special angle strikes I will settle the respective finger. If it’s sine, square root the number of fingers on the left of the settled finger and divide it by 2; if it’s cosine, do the same but on the right; if it’s tangent, divide number of fingers on the left by number of fingers on the right. No need to memorise + no need calculator yays
