We decided to effect some changes in the math curriculum w. r. t. Trigonometry for the new curriculum for some reasons. One of the changes is that of the inverse ratios that are no longer being taught at school level. The other one is that of all identities that include inverses that they are no longer in the school curriculum. I taught those were informed decisions when I first looked at the NCS, but now I am totally against those changes and wish they were retained.
The development that I thought would have been introduced at school level is that of radian measurement compared to degrees. This will better explain the issues of accuracy when it comes to practical problem solving in trigonometry.
We need to make changes for better understanding of our sciences and applies sciences, not just for the sakes of changes.
I am really concerned and wish that our math curriculum be reviewed, not unless if someone can fully convince me as I believe what I have read in the NCS does not convince me.
