This thesis discusses some inequalities obtained from the triangle inequality in normed spaces. The results obtain two inequalities which are another form of the Clarkson distance and a special form of the Maligranda inequality. The role of Tapia’s semi inner product in obtaining the Cauchy-Schwarz inequality in normed spaces is also presented in this thesis. The results are used to analyze the relationship between triangle inequality and Cauchy-Schwarz inequality in inner product spaces. In addition, Tapia’s semi inner product also contributes to form another representation of the Cauchy-Schwarz inequality in inner product spaces. %K Ketaksamaan Cauchy-Schwarz, Ketaksamaan Segitiga, Ruang Bernorma, Ruang Inner Produk, Semi Inner Produk Tapia %D 2024 %I UIN SUNAN KALIJAGA YOGYAKARTA %L digilib66479
