SUMMARY In KCalc, the trigonometric functions and logs are capitalised. This is not the standard way these functions are written, which is all lower case. STEPS TO REPRODUCE Open KCalc and enter Science mode. OBSERVED RESULT The buttons down the left say "Sin", "Cos", "Tan", "Log" and "Ln". EXPECTED RESULT "sin", "cos", "tan", "log" (or maybe "lg") and "ln" SOFTWARE/OS VERSIONS All ADDITIONAL INFORMATION The hyperbolic trigonometric functions accessed through the "Hyp" key, should probably be lower case.
