[QUOTE="BMW9700, post: 360123, member: 49"] as i was taught in shool the " BODMAS" priority B=brackets O= of or multiply D= division M=mutliply A=addition S=subtract in a similar way, sine, cosine and tangent of an angle in a right angled triangle.. sir charles tan = Old Harry And His Old Aunt S(sir)= O(old)/H(harry) C(charles)A(and)/H(his) T(tan)=O(old)/A(aunt) that is:pythogaras theorem: sine of an angle= opposite /hypotenuse cosine of an angle= adjacent/hypotenuse tangent of an angle=opposite/adjacent always works and i still use it as an engineer now...ha ha..really appreciate my teacher mrs yeoh... regards [/QUOTE]
